Iwasaki Yudai db21941d1d *: 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.

lorneli 63aa64d240 lease: use monotime in time.Time for Go 1.9 
The golang/time package tracks monotonic time in each time.Time
returned by time.Now function for Go 1.9.

Use time.Time to measure whether a lease is expired and remove
previous pkg/monotime. Use zero time.Time to mean forever. No
expiration when expiry.IsZero() is true.

Anthony Romano 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.

Gyu-Ho Lee 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.

Anthony Romano 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.

fanmin shi e7f4010cca lease: Use monotonic time in lease

Xiang Li 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.

Anthony Romano be7d573366 lease: store server-decided TTL in lease

Anthony Romano 9113a27bde lease: grant consistent lease IDs 
When raft broadcasts a Grant to all nodes, all nodes must

a lease will fail since the lease ID is node-dependent.

Xiang Li 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.
