Use bucket_space metric in retirement
This makes the Cluster Controller use the
vds.datastored.bucket_space.buckets_total, dimension bucketSpace=default, to
determine whether a content node manages zero buckets, and if so, will allow
the node to go permanently down. This is used when a node is retiring, and it
is to be removed from the application.
The change is guarded by the use-bucket-space-metric, default true. If the new
metric doesn't work as expected, we can revert to using the current/old metric
by flipping the flag. The flag can be controlled per application.
