Determine Active BIG-IP about f5-sca-securitystack

[codygreen]

big-ip-1 will perform a tmsh run /sys failover standby at the end of cloud-init to force big-ip-2 to always be active.

[vinnie357]

Examples for status:

root@(autobigip1)(cfg-sync In Sync)(Peer Time Out of Sync)(/Common)(tmos)# show sys failover
Failover standby for 0d 00:02:55

root@(autobigip2)(cfg-sync In Sync)(Peer Time Out of Sync)(/Common)(tmos)# show sys failover
Failover active for 0d 00:12:36

example tests:

tmsh show sys failover | grep standby
tmsh show sys failover | grep active

tmsh show sys failover | awk '{print $2}'
