proxy: handle authed snapshot request in grpcproxy
...
Like the previous commit 10f783efdd12, this commit lets grpcproxy
forward an auth token supplied by its client in an explicit
manner. snapshot is a stream RPC so this process is required like
watch.

grpcproxy: Disable fast fail on lease grant call to cluster
...
Problem Observed
----------------
When there is no etcd process behind the proxy,
clients repeat resending lease grant requests without delay.
This behavior can cause abnormal resource consumption on CPU/RAM and
network.
Problem Detail
--------------
`LeaseGrant()` uses a bare protobuf client to forward requests.
However, it doesn't use `grpc.FailFast(false)`, which means the method returns
an `Unavailable` error immediately when no etcd process is available.
In clientv3, `Unavailable` errors are not considered the "Halt" error,
and library retries the request without delay.
Both clients and the proxy consume much CPU cycles to process retry requests.
Resolution
----------
Add `grpc.FailFast(false))` to `LeaseGrant()` of the `leaseProxy`.
This makes the proxy not to return immediately when no etcd process is
available. Clients will simply timeout requests instead.

grpcproxy/cache: only check compaction revision for historical revisions
...
Since the current revision is 0, it'll always be less than the compaction
revision. If the proxy sees a compaction, it would always reject the
current revision requests since it's less than the compaction revision.
Instead, check if the revision is historical before trying to reject on
compaction revision.
