Implement OSPF md5 digest authentication

[snuffy22]

Looking in the ospf.yml file there is a mention of digest as a dict.

Mention of digest was recently removed from the documentation, but with our feature we could add back to the table easily enough.

Is it worth making it an actual dict, or do we change it to a 'str' and just support the single id

    digest:
      _remove_when_false: True
      type: dict
      _keys:
        id: { type: int, min_value: 1, max_value: 32 }
        key: { type: str }

I have done a small test with the dict method and IOL / FRR / RouterOS7 and it seems ok.
Granted I have not done the extra test / transformation changes

Does that break existing labs ?

@DanPartelly
So there are no 'integration' test labs that use it.
Also there is no ansible template's using digest for OSPF.

It was never implemented. The first few platforms I worked on didn't have it, and then I guess we stopped looking. Did you find one that works?

Because nothing ever happens in the configuration templates ;)
