OSPF database support (ietf-ospf.yang)

[jovatn]

Description

List OSPF database via NETCONF is not supported, as the associated yang branch of "ietf-ospf.yang" is deviated as not supported by "infix-routing.yang".
This feature request concerns listing what is currently available via CLI "show ospf database" also via YANG.

Additional Information

The database branch of the "ietf-ospf" yang model is huge. Determining what is supported by Infix today is the first step in order to suggest the scope for this feature request.
An rudimentary example of what can be shown by CLI today is given below.

I include a discussion proposal for infix-routing.yang for ospf database support in infix.
infix-routing@2024-09-16.yang.txt

A diff towards the current infix-routing yang is also provided
diff-ospf-database.txt

In short, the idea is to open up support for OSPF database in "ietf-ospf.yang" for OSPFv2, but skipping any "opaque LSA" support. Hopefully this matches what FRR gives us. See the "ro ospf:database" branch in the pyang output below.
