Reworks the sidecar controller to accept ComputedRoutes as an input and use it to generate appropriate ProxyStateTemplate resources containing L4/L7 mesh configuration.
The renaming of files from oss -> ce caused incorrect snapshots
to be created due to ce writes now happening prior to ent writes.
When this happens various entities will attempt to be restored
from the snapshot prior to a partition existing and will cause a
panic to occur.
* Refactors the leafcert package to not have a dependency on agent/consul and agent/cache to avoid import cycles. This way the xds controller can just import the leafcert package to use the leafcert manager.
The leaf cert logic in the controller:
* Sets up watches for leaf certs that are referenced in the ProxyStateTemplate (which generates the leaf certs too).
* Gets the leaf cert from the leaf cert cache
* Stores the leaf cert in the ProxyState that's pushed to xds
* For the cert watches, this PR also uses a bimapper + a thin wrapper to map leaf cert events to related ProxyStateTemplates
Since bimapper uses a resource.Reference or resource.ID to map between two resource types, I've created an internal type for a leaf certificate to use for the resource.Reference, since it's not a v2 resource.
The wrapper allows mapping events to resources (as opposed to mapping resources to resources)
The controller tests:
Unit: Ensure that we resolve leaf cert references
Lifecycle: Ensure that when the CA is updated, the leaf cert is as well
Also adds a new spiffe id type, and adds workload identity and workload identity URI to leaf certs. This is so certs are generated with the new workload identity based SPIFFE id.
* Pulls out some leaf cert test helpers into a helpers file so it
can be used in the xds controller tests.
* Wires up leaf cert manager dependency
* Support getting token from proxytracker
* Add workload identity spiffe id type to the authorize and sign functions

Add support for querying tokens by service name
The consul-k8s endpoints controller has a workflow where it fetches all tokens.
This is not performant for large clusters, where there may be a sizable number
of tokens. This commit attempts to alleviate that problem and introduces a new
way to query by the token's service name.
Fix issue where agentless endpoints would fail to populate after snapshot restore.
Fixes an issue that was introduced in #17775. This issue happens because
a long-lived pointer to the state store is held, which is unsafe to do.
Snapshot restorations will swap out this state store, meaning that the
proxycfg watches would break for agentless.

Prevent partial application of Envoy extensions
Ensure that non-required extensions do not change xDS resources before
exiting on failure by cloning proto messages prior to applying each
extension.
To support this change, also move `CanApply` checks up a layer and make
them prior to attempting extension application, s.t. we avoid
unnecessary copies where extensions can't be applied.
Last, ensure that we do not allow panics from `CanApply` or `Extend`
checks to escape the attempted extension application.
* Fix topoloy intention with mixed connect-native/normal services.
If a service is registered twice, once with connect-native and once
without, the topology views would prune the existing intentions. This
change brings the code more in line with the transparent proxy behavior.

* Consider a service connect-native as soon as one instance is.
* api-gateway: subscribe to bound-api-gateway only after receiving api-gateway
This fixes a race condition due to our dependency on having the listener(s) from the api-gateway config entry in order to fully and properly process the resources on the bound-api-gateway config entry.

### Description
<!-- Please describe why you're making this change, in plain English.
-->
- Currently the jwt-auth filter doesn't take into account the service
identity when validating jwt-auth, it only takes into account the path
and jwt provider during validation. This causes issues when multiple
source intentions restrict access to an endpoint with different JWT
providers.
- To fix these issues, rather than use the JWT auth filter for
validation, we use it in metadata mode and allow it to forward the
successful validated JWT token payload to the RBAC filter which will
make the decisions.
This PR ensures requests with and without JWT tokens successfully go
through the jwt-authn filter. The filter however only forwards the data
for successful/valid tokens. On the RBAC filter level, we check the
payload for claims and token issuer + existing rbac rules.
### Testing & Reproduction steps

to replicate
* Call out any important/ relevant unit tests, e2e tests or integration
tests you have added or are adding

- This test covers a multi level jwt requirements (requirements at top
level and permissions level). It also assumes you have envoy running,
you have a redis and a sidecar proxy service registered, and have a way
to generate jwks with jwt. I mostly use:
https://www.scottbrady91.com/tools/jwt for this.
- first write your proxy defaults
```
Kind = "proxy-defaults"
name = "global"
config {
protocol = "http"
}
```
- Create two providers
```
Kind = "jwt-provider"
Name = "auth0"
Issuer = "https://ronald.local"
JSONWebKeySet = {
Local = {
JWKS = "eyJrZXlzIjog....."
}
}
```
```
Kind = "jwt-provider"
Name = "okta"
Issuer = "https://ronald.local"
JSONWebKeySet = {
Local = {
JWKS = "eyJrZXlzIjogW3...."
}
}
```
- add a service intention
```
Kind = "service-intentions"
Name = "redis"
JWT = {
Providers = [
{
Name = "okta"
},
]
}
Sources = [
{
Name = "*"
Permissions = [{
Action = "allow"
HTTP = {
PathPrefix = "/workspace"
}
JWT = {
Providers = [
{
Name = "okta"
VerifyClaims = [
{
Path = ["aud"]
Value = "my_client_app"
},
{
Path = ["sub"]
Value = "5be86359073c434bad2da3932222dabe"
}
]
},
]
}
},
{
Action = "allow"
HTTP = {
PathPrefix = "/"
}
JWT = {
Providers = [
{
Name = "auth0"
},
]
}
}]
}
]
```
- generate 3 jwt tokens: 1 from auth0 jwks, 1 from okta jwks with
different claims than `/workspace` expects and 1 with correct claims
- connect to your envoy (change service and address as needed) to view
logs and potential errors. You can add: `-- --log-level debug` to see
what data is being forwarded
```
consul connect envoy -sidecar-for redis1 -grpc-addr 127.0.0.1:8502
```
- Make the following requests:
```
curl -s -H "Authorization: Bearer $Auth0_TOKEN" --insecure --cert leaf.cert --key leaf.key --cacert connect-ca.pem https://localhost:20000/workspace -v
RBAC filter denied
curl -s -H "Authorization: Bearer $Okta_TOKEN_with_wrong_claims" --insecure --cert leaf.cert --key leaf.key --cacert connect-ca.pem https://localhost:20000/workspace -v
RBAC filter denied
curl -s -H "Authorization: Bearer $Okta_TOKEN_with_correct_claims" --insecure --cert leaf.cert --key leaf.key --cacert connect-ca.pem https://localhost:20000/workspace -v
Successful request
```

### Description
This is to correct a code problem because this assumes all segments, but
when you get to Enterprise, you can be in partition that is not the
default partition, in which case specifying all segments does not
validate and fails. This is to correct the setting of this filter with
`AllSegments` to `true` to only occur when in the the `default`
partition.

Updating RootPKIPath but not IntermediatePKIPath would not update

This PR fixes a bug that was introduced in:
https://github.com/hashicorp/consul/pull/16021
A user setting a protocol in proxy-defaults would cause tproxy implicit
upstreams to not honor the upstream service's protocol set in its
`ServiceDefaults.Protocol` field, and would instead always use the
proxy-defaults value.
Due to the fact that upstreams configured with "tcp" can successfully contact
upstream "http" services, this issue was not recognized until recently (a
proxy-defaults with "tcp" and a listening service with "http" would make
successful requests, but not the opposite).
As a temporary work-around, users experiencing this issue can explicitly set
the protocol on the `ServiceDefaults.UpstreamConfig.Overrides`, which should
take precedence.
The fix in this PR removes the proxy-defaults protocol from the wildcard
upstream that tproxy uses to configure implicit upstreams. When the protocol
was included, it would always overwrite the value during discovery chain
compilation, which was not correct. The discovery chain compiler also consumes
proxy defaults to determine the protocol, so simply excluding it from the
wildcard upstream config map resolves the issue.

Querying for "test-node.node.dc-test.consul" will faile, because the
code was trimming "test.consul" instead of just ".consul"

For consistency, resource type names must follow these rules:
- `Group` must be snake case, and in most cases a single word.
- `GroupVersion` must be lowercase, start with a "v" and end with a number.
- `Kind` must be pascal case.
These were chosen because they map to our protobuf type naming
conventions.

Fix issue with streaming service health watches.
This commit fixes an issue where the health streams were unaware of service
export changes. Whenever an exported-services config entry is modified, it is
effectively an ACL change.
The bug would be triggered by the following situation:
- no services are exported
- an upstream watch to service X is spawned
- the streaming backend filters out data for service X (due to lack of exports)
- service X is finally exported
In the situation above, the streaming backend does not trigger a refresh of its
data. This means that any events that were supposed to have been received prior
to the export are NOT backfilled, and the watches never see service X spawning.
We currently have decided to not trigger a stream refresh in this situation due
to the potential for a thundering herd effect (touching exports would cause a
re-fetch of all watches for that partition, potentially). Therefore, a local
blocking-query approach was added by this commit for agentless.
It's also worth noting that the streaming subscription is currently bypassed
most of the time with agentful, because proxycfg has a `req.Source.Node != ""`
which prevents the `streamingEnabled` check from passing. This means that while
agents should technically have this same issue, they don't experience it with
mesh health watches.
Note that this is a temporary fix that solves the issue for proxycfg, but not
service-discovery use cases.
* agent: remove agent cache dependency from service mesh leaf certificate management
This extracts the leaf cert management from within the agent cache.
This code was produced by the following process:
1. All tests in agent/cache, agent/cache-types, agent/auto-config,
agent/consul/servercert were run at each stage.
- The tests in agent matching .*Leaf were run at each stage.
- The tests in agent/leafcert were run at each stage after they
existed.
2. The former leaf cert Fetch implementation was extracted into a new
package behind a "fake RPC" endpoint to make it look almost like all
other cache type internals.
3. The old cache type was shimmed to use the fake RPC endpoint and
generally cleaned up.
4. I selectively duplicated all of Get/Notify/NotifyCallback/Prepopulate
from the agent/cache.Cache implementation over into the new package.
This was renamed as leafcert.Manager.
- Code that was irrelevant to the leaf cert type was deleted
(inlining blocking=true, refresh=false)
5. Everything that used the leaf cert cache type (including proxycfg
stuff) was shifted to use the leafcert.Manager instead.
6. agent/cache-types tests were moved and gently replumbed to execute
as-is against a leafcert.Manager.
7. Inspired by some of the locking changes from derek's branch I split
the fat lock into N+1 locks.
8. The waiter chan struct{} was eventually replaced with a
singleflight.Group around cache updates, which was likely the biggest
net structural change.
9. The awkward two layers or logic produced as a byproduct of marrying
the agent cache management code with the leaf cert type code was
slowly coalesced and flattened to remove confusion.
10. The .*Leaf tests from the agent package were copied and made to work
directly against a leafcert.Manager to increase direct coverage.
I have done a best effort attempt to port the previous leaf-cert cache
type's tests over in spirit, as well as to take the e2e-ish tests in the
agent package with Leaf in the test name and copy those into the
agent/leafcert package to get more direct coverage, rather than coverage
tangled up in the agent logic.
There is no net-new test coverage, just coverage that was pushed around
from elsewhere.
This includes prioritize by localities on disco chain targets rather than
resolvers, allowing different targets within the same partition to have
different policies.
