Nic Cope 9b243e9d90 Copy etcd client debug level logic from upstream 
Replicated from https://github.com/etcd-io/etcd/blob/v3.5.4/client/v3/logger.go#L47

The logic of this function doesn't make a lot of sense to me, but
copying it will avoid any behaviour change.

Nic Cope 463756f91d Share a single etcd3 client logger across all clients 
Currently the API server creates one etcd client per CRD. If clients
aren't provided a logger they'll each create their own. These loggers
can account for ~20% of API server memory consumption on a cluster with
hundreds of CRDs.

Nic Cope ef17269e10 Disable the etcd3 client logger 
This logger is responsible for 20% of the API server's memory usage when
many CRDs are installed. See the below issue for more context.

Lukasz Szaszkiewicz 8fa48ed99b etcd-client starts retrying transient errors from the etcd cluster 
This PR enables unaryClientInterceptor in conjunction with Prometheus interceptor.
Previously it was simply overwritten by the Prometheus interceptor.
As a result etcd client didn't attempt to retry certain errors.

The unaryClientInterceptor is important because it knows how to retry all sorts of errors from the etcd cluster. It will make the API server more resilient to failures -  end users won't see certain errors.
The full list of retriable (codes.Unavailable) errors can be found at https://github.com/etcd-io/etcd/blob/main/api/v3rpc/rpctypes/error.go#L72

Walter Fender da748a626b Add support for konnectivity service to the etcd3 client. 
If konnectivity service is enabled, the etcd client will now use it.
This did require moving a few methods to break circular dependencies.

Factored in feedback from lavalamp and wenjiaswe.

Gyuho Lee 1d75397d46 k8s/apiextensions-apiserver/test/integration: block etcd client creation until connection is up 
The new etcd balancer (>3.3.14, 3.4.0) uses an asynchronous resolver for
endpoints. Without "WithBlock", the client may return before the
connection is up.
