Ensure public/management VIP is running on host where HAproxy is working.

After 3 failures on given node, HAproxy will be stopped on that node.
After 120s corosync will reset fail-count for this resource, and
administrator can manually start resource again.

If no manually intervention is made, cluster will start this resource
after 15m (cluster-recheck-interval).

Let kernel kill dead TCP connections

1) Kill dead tcp connections in a more effective way:
configure the keepalive routines to wait for 30 secs before sending
the first keepalive probe, and then resend it every 8 seconds.
If no ACK response is received for 3 tries, mark the connection
as broken.
(The defaults are 7200, 75, 9 respectively and provide a *very* poor logic
for dead connections tracking and failover as well)
http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/usingkeepalive.html
2) Set report_interval to 60 seconds and service_down_time to 180
seconds for Nova to let kernel kill dead connections.
3) Fix missing report_interval param usage in nova class.
4) Provide a new openstack::keepalive class in order to configure
networking related sysctls during the 'netconfig' stage.

Fix eval exit code in dockectl check function

Changing "while !" to "until" in order to pass "eval" exit code
correctly to the output when checking docker containers.

Also fixing multiple check for a single container logic.

Also fixing astute container check - "naily" rabbitmq exchange
appears only after first deployment. It should not be there right
after Fuel node deployment.
