Implement necessary enhancements for RAN Sub-net Slicing: Consider both scenarios:

Scenario 1: RAN NSSMF in ONAP triggers OOF for RAN NSSI selection with RAN NSST. OOF shall provide Slice profiles for RAN NFs, FH and BH subnets when selecting a new RAN NSSI. Subsequently, when OOF is triggered for RAN NFs NSSI, OOF returns a suitable NSSI.

Scenario 2: OOF is triggered for RAN NSSI selection with RAN (NF) NSST. OOF returns a suitable RAN (NF) NSSI.
