fix: make get_domains parameters optional

[tien]

I'm trying to generate a client from this OpenAPI spec. And it appears that the parameter type for get_domains is incorrect.

Please base your PR on and target to development branch.

Looks like the validator is just buggy and won't accept the allOf syntax :v

So I've replaced it with another one, also with added bonus of this one working with relative paths.

This is too much of a change, looking at various documentation, e.g. Swagger it seems what you want to add is not valid/possible plus invalid syntax.

Instead of

        parameters:
          - allOf:
            - $ref: 'domains.yaml#/components/parameters/type'
            - required: false
          - allOf:
            - $ref: 'domains.yaml#/components/parameters/kind'
            - required: false
          - allOf:
            - $ref: 'domains.yaml#/components/parameters/domain'
            - required: false

it should rather be

        parameters:
            - $ref: 'domains.yaml#/components/parameters/type'
              required: false
            - $ref: 'domains.yaml#/components/parameters/kind'
              required: false
            - $ref: 'domains.yaml#/components/parameters/domain'
              required: false

but even this is invalid because of

(screenshot from my link above) and would need to be added further up in this endpoint definition (there is already a parameters object).

The validator change you suggest does not solve the issue, it just doesn't check for this requirement of the OpenAPI specs and, hence, is incomplete.

What we'd need instead is to define new endpoints and use referencing to keep copy-pasting minimal:

+GET /domains
+GET /domains/{type}
+GET /domains/{type}/{kind}
 GET /domains/{type}/{kind}/{domain}

All other (POST, DELETE, PUT) require the parameters. And this then also for

+GET /groups
 GET /groups/{name}
+GET /clients
 GET /clients/{client}
+GET /lists
 GET /lists/{list}

@DL6ER I've undo the unnecessary changes & split the endpoints into multiple ones as requested.
