FailoverPolicy resources are name-aligned with the Service they control.
They also contain a list of possible failover destinations that are References
to other Services.
The ACLs should be:
- list: (default)
- read: service:<resource_name>:read
- write: service:<resource_name>:write + service:<destination_name>:read (for any destination)
The ACLs.Read hook for a resource only allows for the identity of a
resource to be passed in for use in authz consideration. For some
resources we wish to allow for the current stored value to dictate how
to enforce the ACLs (such as reading a list of applicable services from
the payload and allowing service:read on any of them to control reading the enclosing resource).
This change update the interface to usually accept a *pbresource.ID,
but if the hook decides it needs more data it returns a sentinel error
and the resource service knows to defer the authz check until after
fetching the data from storage.

Ensure that configuring a FailoverPolicy for a service that is reachable via a xRoute or a direct upstream causes an envoy aggregate cluster to be created for the original cluster name, but with separate clusters for each one of the possible destinations.

Previously, when using implicit upstreams, we'd build outbound listener per destination instead of one for all destinations. This will result in port conflicts when trying to send this config to envoy.
This PR also makes sure that leaf and root references are always added (before we would only add it if there are inbound non-mesh ports).
Also, black-hole traffic when there are no inbound ports other than mesh
HTTPRoute, GRPCRoute, TCPRoute, and Upstreams resources contain inner
Reference fields. We want to ensure that components of those reference Tenancy
fields left unspecified are defaulted using the tenancy of the enclosing resource.
As the underlying helper being used to do the normalization calls the function
modified in #18822, it also means that the PeerName field will be set to "local" for
now automatically to avoid "local" != "" issues downstream.

Reworks the sidecar controller to accept ComputedRoutes as an input and use it to generate appropriate ProxyStateTemplate resources containing L4/L7 mesh configuration.
When one resource contains an inner field that is of type *pbresource.Reference we want the
Tenancy to be reasonably defaulted by the following rules:
1. The final values will be limited by the scope of the referenced type.
2. Values will be inferred from the parent's tenancy, and if that is insufficient then using
the default tenancy for the type's scope.
3. Namespace will only be used from a parent if the reference and the parent share a
partition, otherwise the default namespace will be used.
Until we tackle peering, this hard codes an assumption of peer name being local. The
logic for defaulting may need adjustment when that is addressed.
* 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

This new controller produces an intermediate output (ComputedRoutes) that is meant to summarize all relevant xRoutes and related mesh configuration in an easier-to-use format for downstream use to construct the ProxyStateTemplate.
It also applies status updates to the xRoute resource types to indicate that they are themselves semantically valid inputs.

This commit adds support for transparent proxy to the sidecar proxy controller. As we do not yet support inferring destinations from intentions, this assumes that all services in the cluster are destinations.
* This controller generates and saves ProxyStateTemplate for sidecar proxies.
* It currently supports single-port L4 ports only.
* It keeps a cache of all destinations to make it easier to compute and retrieve destinations.
* It will update the status of the pbmesh.Upstreams resource if anything is invalid.
* This commit also changes service endpoints to include workload identity. This made the implementation a bit easier as we don't need to look up as many workloads and instead rely on endpoints data.
We explicitly enumerate the allowed protocols in validation, so this
change is necessary to use the new enum value.
Also add tests for enum validators to ensure they stay aligned to
protos unless we explicitly want them to diverge.
