The patch adds events that match on gateway chassis hosting the cr lrp ports for the given floating ips. If there is a failover detected and the CR LRP moves to a different chassis, all the floating IPs are moved to with it. It also adds functional tests for agent and its watchers. The watchers part can be improved and the functional framework can be used further to extend testing coverage. Closes-Bug: #2056477 Change-Id: Ia857df921eb32e5e822fc790064179b07351d8d3 Signed-off-by: Jakub Libosvar <libosvar@redhat.com>
