Adds functionality to generate bash script which verifies health of current keepalived instance by pinging all available and configured GW addresses. This functionality supports IPv4 and IPv6 by detecting needed ping version using netaddr. DocImpact: Added a new parameter to 'l3_agent.ini' named 'ha_vrrp_health_check_interval' which is by default set to 0 (disabled). Values > 0 designate health check functionality should be enabled. Requires allowed ICMP ECHO_REQUEST because that is disabled by default.
