Emit single metric for how out of sync the cluster data is
With these changes the cluster controller continuously maintains
a global aggregate across all content nodes that represents the
number of pending and total buckets per bucket space. This aggregate
can be sampled in O(1) time.
An explicit metric `cluster-buckets-out-of-sync-ratio` has been
added, and the value is also emitted as part of the cluster state
REST API. Note: only emitted when statistics have been received
from _all_ distributors for a particular cluster state, as it would
otherwise potentially represent a state somewhere arbitrary between
two or more distinct states.
