[BUG] Masquerading policies issue in Undercloud to establish SNAT communication between VM and public network

[pradiptapks]

Jetpack configured external gateway IP in Director node. But due to lack of Masquerading policy the tenant VM with FIP unable to communicate internet.

I have tested below script in Director node where SNAT communication from VM to the Internet is working perfectly. So it would great if we can integrate the similar functionality post deployment of overcloud in Jetpack.

Reopen this BZ, as I came across the issue 2nd time 1029u host.

The following section needs to enhance:
