Add support for 'modify security firewall global-fqdn-policy dns-resolver resolvername'

[Arganox]

Is your feature request related to a problem? Please describe.

Creating an AFM policy then uses fqdns via class Firewall_Address_List.

....
"fwAllowedSites": {
"class": "Firewall_Address_List",
                    "fqdns": [
                        "www.ifconfig.com",
                        "www.google.com"
                    ]
}
...

When I manually add the dns-resolver tenant creation works just fine. I've been told by Stanislas PIRON(F5) on the Slack channel that this is not yet supported by DO.

Describe the solution you'd like

DO-ification of tmsh command: modify security firewall global-fqdn-policy dns-resolver resolvername

Describe alternatives you've considered

• Manually link DNS Resolver
• Config merge with DNS resolver settings included
• TMSH command via terraform after DO to link the resolver to AFM
