More flexible firewall options in NSX-T

Allow free-text entry of DNS names, IP ranges & port settings

Objects need to be created in NSX-T for firewall ports & protocols, and DNS targets. This negates the spirit of self-service, and there is also a limit on the number that can be created in NSX-T.

Example/Use case(s):
Allow more flexibility for entering IP ranges, or DNS for the source/destination.
Allow custom services to be configured rather than just a pre-defined list.
