4dff7aaa2a clientv3: change keepAlive Close() to close() 
keepAlive is a private struct that belongs to clientv3 pkg and shouldn't expose a public Close() method.

6a33f0ffd5 clientv3: make balancer respect FastFail 
The simpleBalancer.Get() blocks grpc.Invoke() even when the Invoke() is called
with the FailFast option. Therefore currently any requests with the
FastFail option actually doesn't fail fast. They get blocked when there is
no endpoints available.
Get() method needs to respect the BlockingWait option when
picks up an endpoint address from the list and fail immediately when the option is
enabled and no endpoint is available.

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.

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.
