Title: gh-1412 - Rework swapnode for OSS

+Change swapnode, so that it works on the underlying groups that
are generated from the environment clusters.
+Also introduce an implicit "spares" group
+Add various cmdline options to manipulate spares and swaps
+NB: an environment update that updates the cluster, will not override
the 'live' groups, warnings will ensure instead.
The environment can be forced via updtdalienv to create the groups if
desired.
