louisgong 4c8b97679c Use dynamic size watch-cache. 
If all cached events occur inside eventFreshDuration, increase cache capacity by 2x.
Decrease cache capacity by 2x when recent half events occur outside eventFreshDuration.

Michael Gasch 0cdbc006ea Add etcd WithRequireLeader option to API watches 
Watches against etcd in the API server can hang forever if the etcd
cluster loses quorum, e.g. the majority of nodes crashes. This fix
improves responsiveness (detection and reaction time) of API server
watches against etcd in some rare (but still possible) edge cases so
that watches are terminated with `"etcdserver: no leader"
(ErrNoLeader)`.

Implementation behavior described by jingyih:

```
The etcd server waits until it cannot find a leader for 3 election
timeouts to cancel existing streams. 3 is currently a hard coded
constant. The election timeout defaults to 1000ms.

If the cluster is healthy, when the leader is stopped, the leadership
transfer should be smooth. (leader transfers its leadership before
stopping). If leader is hard killed, other servers will take an election
timeout to realize leader lost and start campaign.
```

For further details, discussion and validation see

and https://github.com/etcd-io/etcd/issues/8980.

Monis Khan f5c1e085ed storage: confirm that paging and predicate filtering work together 
This change adds the TestListContinuationWithFilter test which
confirms that paging with a predicate that does not match everything
results in the correct amount of calls to TransformFromStorage and
KV.Get.  The partial result of each paging call is also asserted.
