The DestroyFunc functions returned by generic.NewRawStorage is never
called when we do a StartTestServer() in the test suite. For a quick
hack for now, added TrackStorageCleanup/RegisterStorageCleanup and
CleanupStorage. Note that unless TrackStorageCleanup is called (which
is called only from the test suite) the other two methods are
no-ops essentially. So no change in behavior at runtime. This vastly
brings down the number of goroutines that are left behind when this
test is executed and should reduce if not eliminate the flakiness
of TestCRD

Pick a reasonable middle ground between allocating larger chunks of
memory (2048 * ~500b for pod slices) and having many small allocations
as the list is resized by preallocating capacity based on the expected
list size. At worst, we'll allocate a 1M slice for pods and only add
a single pod to it (if the selector is very specific).

The etcd3 storage now attempts to fill partial pages to prevent clients
having to make more round trips (latency from server to etcd is lower
than client to server). The server makes repeated requests to etcd of
the current page size, then uses the filter function to eliminate any
matches. After this change the apiserver will always return full pages,
but we leave the language in place that clients must tolerate it.
Reduces tail latency of large filtered lists, such as viewing pods
assigned to a node.

This commit adds an option for controlling request of compaction to
etcd3 from apiserver. There is a situation that apiserver cannot fully
own its etcd cluster (e.g. sharing it with canal). In such a case,
apiserver should have limited access in terms of etcd's auth
functionality so it don't have a priviledge to issue compaction
requests. It means that the compaction requests should be issued by
other component and apiserver's compaction requests are needless.
For such use cases, this commit adds a new flag
`storagebackend.Config.CompactionInterval`. If the flag is non 0,
apiserver issues the compaction requests like current behaviour (the
default is 5 minutes). If it is 0, apiserver doesn't issue the
requests. It can be configured with a newly added option of apiserver
`--etcd-compaction-interval`.

In GuaranteedUpdate, if it was called with a suggestion (e.g. via the
watch cache), and the suggested object is stale, perform a live lookup
and then retry the update.
