Monis Khan 8d68e6f323 Load encryption config once 
This change updates the API server code to load the encryption
config once at start up instead of multiple times.  Previously the
code would set up the storage transformers and the etcd healthz
checks in separate parse steps.  This is problematic for KMS v2 key
ID based staleness checks which need to be able to assert that the
API server has a single view into the KMS plugin's current key ID.

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.

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
