lessor: extend leases on promote if expires will be rate limited
...
Instead of unconditionally randomizing, extend leases on promotion
if too many leases expire within the same time span. If the server
has few leases or spread out expires, there will be no extension.

lease: use atomics for accessing lease expiry
...
Demote was racing on expiry when LeaseTimeToLive called Remaining. Replace
with intrinsics since the ordering isn't important, but torn writes are
bad.

*: refresh the lease TTL correctly when a leader is elected.
...
The new leader needs to refresh with an extened TTL to gracefully handle
the potential concurrent leader issue. Clients might still send keep alive
to old leader until the old leader itself gives up leadership at most after
an election timeout.

*: add support for lease create and revoke

Basic support for lease operations like create and revoke.
We still need to:
1. attach keys to leases in KV implmentation if lease field is set
2. leader periodically removes expired leases
3. leader serves keepAlive requests and follower forwards keepAlive
requests to leader.
