fbed568b6a 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.

1704443c6d clientv3: only health-check when timeout elapses since last failure 
Otherwise network-partitioned member with active health-check
server would not be gray-listed, making health-balancer stuck
with isolated endpoint.

Also clarifies some log messages.

5096b4ed5d clientv3/ordering: compare and update prevRev atomically 
Several goroutines may call setPrevRev concurrently with different
revisions, all higher than prevRev. Previously all of these goroutines
could set prevRev, so prevRev may be replaced by older one.

If response's revision equals to prevRev, there's no need to call
setPrevRev.

252cab0c13 clientv3: Allow naked LeaseID or int64 for LeaseValue Compare's 
The logical input to Compare would be a LeaseID (type int64) but the
check panics if we give a LeaseID directly. Allow both so that we don't
unnecessarily annoy and confuse the programmer using the API in the most
logical way.

61ebb98e55 leasing: retry on errors from acquire txn 
Gets should retry on transient failure, but the txn inserts a write, skipping
the retry logic in the client. Instead, check the error if the txn should be
retried.
