Bug description:
It would be useful if 'vip' could be handled in a nonHA way
(ie without a related hacluster subordinate).
This could be handled by the charm itself, by adding the
vip as an ip alias to the highest numbered unit (and removing
it from the previous unit, if any) if a setting like
'non-ha-vip' is True.
FWIW from ~ expected usage, I'd suggest above approach
vs leadership election, to prefer the fresh-er units for
the vip, specially for the single-unit case where you'd
want to 'replace' an existing unit (add-unit + remove-unit
previous one).
