Zhang Hua 786906d559 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.

This is a patch for charm-neutron-openvswitch side to support
enable-dvr-snat=True option which allows running gateway components
on compute nodes (as of 19.04 charms, see [6])
