e4a2dcad9e clientv3/integration: ignore closing transport in TestKVPutStoppedServerAndClose 
The grpc "transport is closing" error is rasied when the host is unreachable;
there's no good way to avoid it for a Put.

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).

e8101ddf09 clientv3: throttle reconnection rate 
Client was reconnecting after establishing connections because the lease
and watch APIs were thrashing. Instead, wait a little before accepting
new reconnect requests.

c26eb3f241 clientv3: better serialization for kv and txn connection retry 
If the grpc connection is restored between an rpc network failure
and trying to reestablish the connection, the connection retry would
end up resetting good connections if many operations were
in-flight at the time of network failure.

30a9229f38 clientv3: check stream context in lease keep alive send loop 
If no leases are being kept alive, a connection reset would leak
the send routine since it would only test the stream when sending
keep alives.

22797c7185 clientv3/concurrency: use session lease id for mutex keys 
With randomized keys, if the connection goes down, but the session remains,
the client would need complicated recovery logic to avoid deadlock.
Instead, bind the session's lease id to the lock entry; if a session tries
to reacquire the lock it will reassume its old place in the wait list.

cbd79c666e clientv3: keepaliveonce should have a per call ctx 
KeepAliveOnce should have a per call ctx. Now we have a per
API ctx, but we might do rpc calls mutiple times in a for loop.

To avoid unnecessary routine leak, use per call ctx.

844208d7dd clientv3: retry on switchRemoteAndStream 
If switchRemoteAndStream fails, the whole lease API fails since
the internal routine exits. We should only fail the whole API when
there is a fatal error. For example, we should fail if we fail to
connection to all the endpoints user provided.

If we connect to an endpoint, but fail to create a stream, we should
retry instead of returning error to fail the entire API.
