etcd3/store: support TTL in Create, Update
ref: https://github.com/kubernetes/kubernetes/issues/22448
What's included in the PR?
- Support TTL keys in Create() and Update()
- Simple testing for create
Note
- Have TTL keys in a long window (5min) in one lease. I'm not sure if we should do it right now. We could just implement it as simple as is. Once we have etcd3 work done we could start testing and measuring with some realistic load.
