Update: clean keepalived and radvd instances after pcs cluster stop
Older neutron versions have a bug which makes them leave keepalived and
radvd running even after all neutron services are stopped, preventing
neutron router failover from happening. Router can then get stuck on the
inactive node, like this:
[stack@instack ~]$ neutron l3-agent-list-hosting-router default_router

We need to kill the leftover processes manually to prevent the state
described above from happening.
