Previously, only display the one that has been requested at least once.
Now it shows all metrics, as we do in v3.3 and v3.4+.

etcdserver.
To improve debuggability of etcd v3. Added a grpc interceptor to log
info on incoming requests to etcd server. The log output includes remote
client info, request content (with value field redacted), request
handling latency, response size, etc.
Dependency on zap logger and grpc_middleware is removed during
backporting.
Added checking in logging interceptor. If debug level is disabled, skip
logUnaryRequestStats() to avoid potential performance degradation. (PR #10021)
The context error with cancel code is typically for user cancellation which
should be at debug level. For other error codes we should display a warning.
Fixes#9085
From go-grpc v1.2.0, the number of max streams per client is set to 100
by default by the server side. This change makes it impossible
for third party proxies and custom clients to establish many streams.
gRPC will replace empty strings with nil, but for the embedded case it's
possible for []byte{} to slip in and confuse the single key / >= key
watch logic.
This commit adds a mechanism of handling a case of expired auth token
to clientv3. If a server returns an error code
grpc.codes.Unauthenticated, newRetryWrapper() tries to get a new token
and use it as an option of PerRPCCredential.
Fixes https://github.com/coreos/etcd/issues/7012
Would retry a few times before returning a not primary error that
the client should never see. Instead, use proper timeouts and
then return a request timeout error on failure.
Fixes#6922
