This is the OSS portion of enterprise PR 3822.
Adds a custom gRPC balancer that replicates the router's server cycling
behavior. Also enables automatic retries for RESOURCE_EXHAUSTED errors,
which we now get for free.
* Update api gateway version to latest
* Update website/content/docs/api-gateway/install.mdx
* update to latest apigw version 0.5.1
* update consul and helm version
* Refactoring the peering integ test to accommodate coming changes of other upgrade scenarios.
- Add a utils package under test that contains methods to set up various test scenarios.
- Deduplication: have a single CreatingPeeringClusterAndSetup replace
CreatingAcceptingClusterAndSetup and CreateDialingClusterAndSetup.
- Separate peering cluster creation and server registration.
* Apply suggestions from code review

Adds automation for generating the map of `gRPC Method Name → Rate Limit Type`
used by the middleware introduced in #15550, and will ensure we don't forget
to add new endpoints.
Engineers must annotate their RPCs in the proto file like so:
```
rpc Foo(FooRequest) returns (FooResponse) {
option (consul.internal.ratelimit.spec) = {
operation_type: READ,
};
}
```
When they run `make proto` a protoc plugin `protoc-gen-consul-rate-limit` will
be installed that writes rate-limit specs as a JSON array to a file called
`.ratelimit.tmp` (one per protobuf package/directory).
After running Buf, `make proto` will execute a post-process script that will
ingest all of the `.ratelimit.tmp` files and generate a Go file containing the
mappings in the `agent/grpc-middleware` package. In the enterprise repository,
it will write an additional file with the enterprise-only endpoints.
If an engineer forgets to add the annotation to a new RPC, the plugin will
return an error like so:
```
RPC Foo is missing rate-limit specification, fix it with:
import "proto-public/annotations/ratelimit/ratelimit.proto";
service Bar {
rpc Foo(...) returns (...) {
option (hashicorp.consul.internal.ratelimit.spec) = {
operation_type: OPERATION_READ | OPERATION_WRITE | OPERATION_EXEMPT,
};
}
}
```
In the future, this annotation can be extended to support rate-limit
category (e.g. KV vs Catalog) and to determine the retry policy.
Previously, these endpoints required `service:write` permission on _any_
service as a sort of proxy for "is the caller allowed to participate in
the mesh?".
Now, they're called as part of the process of establishing a server
connection by any consumer of the consul-server-connection-manager
library, which will include non-mesh workloads (e.g. Consul KV as a
storage backend for Vault) as well as ancillary components such as
consul-k8s' acl-init process, which likely won't have `service:write`
permission.
So this commit relaxes those requirements to accept *any* valid ACL token
on the following gRPC endpoints:
- `hashicorp.consul.dataplane.DataplaneService/GetSupportedDataplaneFeatures`
- `hashicorp.consul.serverdiscovery.ServerDiscoveryService/WatchServers`
- `hashicorp.consul.connectca.ConnectCAService/WatchRoots`
Fix agent cache incorrectly notifying unchanged protobufs.
This change fixes a situation where the protobuf private fields
would be read by reflect.DeepEqual() and indicate data was modified.
This resulted in change notifications being fired every time, which
could cause performance problems in proxycfg.
This gets the extensions information for the local service into the snapshot and ExtensionConfigurations for a proxy. It grabs the extensions from config entries and puts them in structs.NodeService.Proxy field, which already is copied into the config snapshot.
Also:
* add EnvoyExtensions to api.AgentService so that it matches structs.NodeService
* extensions: refactor PluginConfiguration into a more generic type
ExtensionConfiguration
Also:
* adds endpoints configuration to lambda golden tests
* uses string constant for builtin/aws/lambda

* add functions for returning the max and min Envoy major versions
- added an UnsupportedEnvoyVersions list
- removed an unused error from TestDetermineSupportedProxyFeaturesFromString
- modified minSupportedVersion to use the function for getting the Min Envoy major version. Using just the major version without the patch is equivalent to using `.0`
* added a function for executing the envoy --version command
- added a new exec.go file to not be locked to unix system
* added envoy version check when using consul connect envoy
* added changelog entry
* added docs change
* added a NS folder and refactored main page into the overview page
* added NS usage page to NS folder
* updated links to NS docs
* updated nav
* addressed feedback from review
* update docs to reflect vault and consul compatibility
* Update website/content/docs/connect/ca/vault.mdx

The new balancer is a patched version of gRPC's default pick_first balancer
which removes the behavior of preserving the active subconnection if
a list of new addresses contains the currently active address.
Removing curl inadvertently dropped the transitive dependency on shadow-utils
which is required for the groupadd executable. Since curl-minimal does not
have this dependency, make it explicit as part of `microdnf install`.
