Gyuho Lee f3385418bb clientv3: fix keepalive send interval when response queue is full 
client should update next keepalive send time
even when lease keepalive response queue becomes full.

Otherwise, client sends keepalive request every 500ms
regardless of TTL when the send is only expected to happen
with the interval of TTL / 3 at minimum.

Hitoshi Mitake b1dd19a7aa *: don't use string literals directly in grpc metadata 
Current etcd code uses the string literals ("token", "authorization")
as field names of grpc and swappger metadata for passing token. It is
difficult to maintain so this commit introduces new constants for the
purpose.

Gyu-Ho Lee 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.

James Shubin 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.

Anthony Romano 61ebb98e55 leasing: retry on errors from acquire txn
