eaa0050d4d *: enforce max lease TTL with 9,000,000,000 seconds 
math.MaxInt64 / time.Second is 9,223,372,036. 9,000,000,000 is easier to
remember/document.

c38c00f7c3 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.

5bba05703c lease: randomize expiry on initial refresh call 
Randomize the very first expiry on lease recovery
to prevent recovered leases from expiring all at
the same time.

42d56d5ef7 lease: acquire BatchTx lock in fakeDeleter 
Revoke expects the BatchTx lock to be held when holding the TxnDeleter
because it updates the lease bucket. The tests don't hold the lock so
it may race with the backend commit loop.

Fixes #7662

e9a0a103e5 *: 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.

9113a27bde lease: grant consistent lease IDs 
When raft broadcasts a Grant to all nodes, all nodes must
agree on the same lease ID. Otherwise, attaching a key to
a lease will fail since the lease ID is node-dependent.

d9ca929a33 *: 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.
