This patch adds microversion 1.32 supporting the forbidden aggregate
expression within existing ``member_of`` queryparam both in
``GET /resource_providers`` and in ``GET /allocation_candidates``.
Forbidden aggregates are prefixed with a ``!``.
We do NOT support ``!`` within the ``in:`` list:
?member_of=in:<agg1>,<agg2>,!<agg3>
but we support ``!in:`` prefix:
?member_of=!in:<agg1>,<agg2>,<agg3>
which is equivalent to:
?member_of=!<agg1>&member_of=!<agg2>&member_of=!<agg3>
where candidate resource providers must not be in agg1, agg2, or agg3.
