Fix panic on 32-bit platforms

Conflicts in tlsutil/config.go were resolved by dropping those changes.
The issue that was fixed in that file is not in 1.10.x.

Update references to the main branch

 Conflicts:
	.github/CONTRIBUTING.md
	website/content/docs/upgrading/instructions/upgrade-to-1-10-x.mdx

The website conflicts seems like it some of the changes on main didn't
make it into the 1.10.x branch, but the content is relevant for 1.10 so
I took the changes from main.

Freddy 645e406ca0 Rename CatalogDestinationsOnly (#10397)
CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.

This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.

Dhia Ayachi 3717ab0991 generate a single debug file for a long duration capture (#10279)
* debug: remove the CLI check for debug_enabled

The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.

Also:
- fix the API client to return errors on non-200 status codes for debug
  endpoints
- improve the failure messages when pprof data can not be collected

Co-Authored-By: Dhia Ayachi <dhia@hashicorp.com>

* remove parallel test runs

parallel runs create a race condition that fail the debug tests

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* extract wait group outside the go routine to avoid a race condition

* capture pprof in a separate go routine

* perform a single capture for pprof data for the whole duration

* add missing vendor dependency

* add a change log and fix documentation to reflect the change

* create function for timestamp dir creation and simplify error handling

* use error groups and ticker to simplify interval capture loop

* Logs, profile and traces are captured for the full duration. Metrics, Heap and Go routines are captured every interval

* refactor Logs capture routine and add log capture specific test

* improve error reporting when log test fail

* change test duration to 1s

* make time parsing in log line more robust

* refactor log time format in a const

* test on log line empty the earliest possible and return

Luke Kysow c816e29ef7 Give descriptive error if auth method not found (#10163)
* Give descriptive error if auth method not found

Previously during a `consul login -method=blah`, if the auth method was not found, the
error returned would be "ACL not found". This is potentially confusing
because there may be many different ACLs involved in a login: the ACL of
the Consul client, perhaps the binding rule or the auth method.

Now the error will be "auth method blah not found", which is much easier
to debug.

R.B. Boyer 145a83e436 connect: update supported envoy versions to 1.18.2, 1.17.2, 1.16.3, and 1.15.4 (#10101)
The only thing that needed fixing up pertained to this section of the 1.18.x release notes:

> grpc_stats: the default value for stats_for_all_methods is switched from true to false, in order to avoid possible memory exhaustion due to an untrusted downstream sending a large number of unique method names. The previous default value was deprecated in version 1.14.0. This only changes the behavior when the value is not set. The previous behavior can be used by setting the value to true. This behavior change by be overridden by setting runtime feature envoy.deprecated_features.grpc_stats_filter_enable_stats_for_all_methods_by_default.

For now to maintain status-quo I'm explicitly setting `stats_for_all_methods=true` in all versions to avoid relying upon the default.

Additionally the naming of the emitted metrics for these gRPC requests changed slightly so the integration test assertions for `case-grpc` needed adjusting.

R.B. Boyer 6a39b47448 Support Incremental xDS mode (#9855)
This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged.

Union of all commit messages follows to give an overarching summary:

xds: exclusively support incremental xDS when using xDS v3

Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail.
Work around a strange older envoy behavior involving empty CDS responses over incremental xDS.
xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support

Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead.
Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client.
xds: pull out checkStreamACLs method in advance of a later commit

xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings

In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty.

This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10.

xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

Iryna Shustava f383452e87 Implement traffic redirection exclusion based on proxy config and user-provided values (#10134)
* Use proxy outbound port from TransparentProxyConfig if provided
* If -proxy-id is provided to the redirect-traffic command, exclude any listener ports
  from inbound traffic redirection. This includes envoy_prometheus_bind_addr,
  envoy_stats_bind_addr, and the ListenerPort from the Expose configuration.
* Allow users to provide additional inbound and outbound ports, outbound CIDRs
  and additional user IDs to be excluded from traffic redirection.
  This affects both the traffic-redirect command and the iptables SDK package.

Freddy c652580b5b Rename "cluster" config entry to "mesh" (#10127)
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.

Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.

freddygv 7cb3f32672 Convert new tproxy structs in api module into ptrs
This way we avoid serializing these when empty. Otherwise users of the
latest version of the api submodule cannot interact with older versions
of Consul, because a new api client would send keys that the older Consul
doesn't recognize yet.

freddygv 7bd51ff536 Replace TransparentProxy bool with ProxyMode
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:

- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.

This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

Add flags to consul connect envoy for metrics merging. (#9768)
Allows setting -prometheus-backend-port to configure the cluster
envoy_prometheus_bind_addr points to.

Allows setting -prometheus-scrape-path to configure which path
envoy_prometheus_bind_addr exposes metrics on.

-prometheus-backend-port is used by the consul-k8s metrics merging feature, to
configure envoy_prometheus_bind_addr to point to the merged metrics
endpoint that combines Envoy and service metrics so that one set of
annotations on a Pod can scrape metrics from the service and it's Envoy
sidecar.

-prometheus-scrape-path is used to allow configurability of the path
where prometheus metrics are exposed on envoy_prometheus_bind_addr.

Alex Dzyoba 098fd1797b command/kv: Add prefix option to kv import command
Currently when data is imported via `consul kv import` it overwrites
keys under the root key. Since `consul kv export` can retrieve data for
the given prefix, i.e. part of the KV tree, importing it under root may
be not what users want.

To mirror prefix behavior from export this PR adds prefix feature to the
import command that adds prefix to all keys that are imported.
