Patch adds a script in the monasca-thresh image that can be used
to check if a topology exists in Storm, and optionally kill it.
This is part of a bug in kolla-ansible where topologies were
not submitted to Storm, but run locally. This patch includes
a topology check script enabled by KOLLA_BOOTSTRAP which will exit
kolla_start if the topology exists, and optionally enables topology
removal (to allow replacement) enabled by TOPOLOGY_REPLACE.
Topology names and various timeouts may be customized. If the
new env variables are not set, existing behavior is unchanged.
