94f81368ae etcdserver: add grpc interceptor to log info on incoming requests to etcd server 
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. Uses zap logger if available,
otherwise uses capnslog.

Also did some clean up on the chaining of grpc interceptors on server
side.

to see what Go version was used to build etcd server.

ec43197344 etcdserver/api/v3rpc: debug user cancellation and log warning for rest 
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.

e0dfc4368f etcdserver: CheckInitialHashKV when "InitialCorruptCheck==true" 
etcdserver: only compare hash values if any

It's possible that peer has higher revision than local node.
In such case, hashes will still be different on requested
revision, but peer's header revision is greater.

etcdserver: count mismatch only when compact revisions are same
