clientv3: start a session with existing lease
...
This change is needed to handle process restarts with elections. When the
leader process is restarted, it should be able to hang on to the leadership
by using the existing lease.

After winning an election or obtaining a lock, we
auto-append a slash after the provided key prefix.
This avoids the previous deadlock due to waiting
on the wrong key.

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.
