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.

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.

b5cde6b321 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.

fef4a79528 lease: force leader to apply its pending committed index for lease operations 
suppose a lease granting request from a follower goes through and followed by a lease look up or renewal, the leader might not apply the lease grant request locally. So the leader might not find the lease from the lease look up or renewal request which will result lease not found error. To fix this issue, we force the leader to apply its pending commited index before looking up lease.

be1f36d97c v3rpc, etcdserver, leasehttp: ctxize Renew with request timeout 
Would retry a few times before returning a not primary error that
the client should never see. Instead, use proper timeouts and
then return a request timeout error on failure.

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.
