clientv3/balancer: mark partitioned member as unhealthy
...
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.

clientv3: wait for ConnectNotify before sending RPCs
...
With slow CPU, gRPC can lag behind with RPCs being sent before
calling 'Up', returning 'no address available' on the first try.

etcdserver, clientv3: handle a case of expired auth token
...
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

clientv3: fix retry logic
...
1. Balancer should setup gRPC error code correctly for retry.
2. We should not mask context error.
