This change makes the etcd package compatible with the existing Go
ecosystem for module versioning.
Used this tool to update package imports:

This changes have started at etcdctl under auth.go, and make changes to stub out everything down into the internal raft. Made changes to the .proto files and regenerated them so that the local version would build successfully.
Update to Go 1.12.5 testing. Remove deprecated unused and gosimple
pacakges, and mask staticcheck 1006. Also, fix unconvert errors related
to unnecessary type conversions and following staticcheck errors:
- remove redundant return statements
- use for range instead of for select
- use time.Since instead of time.Now().Sub
- omit comparison to bool constant
- replace T.Fatal and T.Fatalf in tests with T.Error and T.Fatalf respectively because the goroutine calls T.Fatal must be called in the same goroutine as the test
- fix error strings that should not be capitalized
- use sort.Strings(...) instead of sort.Sort(sort.StringSlice(...))
- use he status code of Canceled instead of grpc.ErrClientConnClosing which is deprecated
- use use status.Errorf instead of grpc.Errorf which is deprecated

status.FromError can return nil, false. We are handling the return values
most places in code but some places we aren't. Fixing it herewith.
Fixes#9117
Previous behavior is when server returns errors, retry
wrapper does not do anything, while passively expecting
balancer to gray-list the isolated endpoint. This is
problematic when multiple endpoints are passed, and
network partition happens.
This patch adds 'endpointError' method to 'balancer' interface
to actively(possibly even before health-check API gets called)
handle RPC errors and gray-list endpoints for the time being,
thus speeding up the endpoint switch.
This is safe in a single-endpoint case, because balancer will
retry no matter what in such case.

With slow CPU, gRPC can lag behind with RPCs being sent before
calling 'Up', returning 'no address available' on the first try.

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.
