Zhang Hua 4c150529b5 Enable keepalived VRRP health check
If you want to have vrrp watch the external networking interface
today, the option ha_vrrp_health_check_interval [1] detects a failure
it re-triggers the transitional change - which works if the external
physical interface fails because the ping will fail.

In fact, we've tried to enable it before [2], but then we had to
revert it [3] due to instability issues [4] in previous releases of
OpenStack. Maybe the previous instability issue [4] was caused by
another keepalived issue mentioned in the comment [5], now I have
tested this option again, it works.

This is how neutron allows monitoring southbound network today, so
I would suggest we add this capability into the charm again.
