Bence Romsics 6c513217c2 ovs-agent: React to DB down just like to server down
When neutron-server is down, ovs-agent waits for it to become available
during agent startup. When neutron-server is up, but it cannot reach the
DB, it can do nothing pretty much the same way. However ovs-agent
reacted differently to this failure. With this patch it reacts the same
way and delays its startup until neutron-server is up together with its
DB.

PluginReportStateAPI has a new version (1.3) in which
has_alive_neutron_server() no longer returns always True, but performs
a DB connection check and returns True/False accordingly. Using this, an
agent can check not just MQ but the server's DB connectivity too.
