8effbda3a7 clientv3: use Endpoints[0] to initialize grpc creds 
Dialing out without specifying TLS creds but giving https uses some
default behavior that depends on passing an endpoint with https to
Dial(), so it's not enough to completely rely on the balancer to supply
endpoints.

Fixes #8008

Also ctx-izes grpc.Dial

d431b64d97 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.

c100e40715 clientv3: only receive from closing streams in Watcher close 
Was overcounting the number of expected closing messages; the resuming
list may have nil entries. Also the full client wasn't closing the watcher
client, only canceling its context, so client closes weren't joining with
the watcher shutdown.

5f5a203e27 clientv3: don't hold client lock while dialing 
Causes async reconnect to block while the client is dialing.

This was also causing problems with the Close error message, so
now Close() will return the last dial error (if any) instead of
clearing it out with a cancel().

6259318521 *: attach auth token as a gRPC credential 
This commit adds a functionality of attaching an auth token to gRPC
connection as a per RPC credential.

For doing this, this commit lets clientv3.Client.Dial() create a
dedicated gRPC connection for doing authentication. With the dedicated
connection, the client calls Authenticate() RPC and obtain its
token. The token is attached to the main gRPC connection with
grpc.WithPerRPCCredentials().

This commit also adds a new option --username to etcdctl (v3). With
this option, etcdctl attaches its auth token to the main gRPC
connection (currently it is not used at all).
