Rename server_uuids parameter to servers in volume module

[gaudenz]

This now looks good from my point of view. But I'd prefer @href to have a quick look at my deprecation commit.

Looks good to me, go ahead and merge at will.

I see a missed opportunity:

What about using a list of objects as param (similar what is returned by the api)?

Advantages:

• comparison of diff may be easier (compare list of objects)
• server by name (no need to query and register the result for uuid of the server in a previous tasks)

by server uuid

- cloudscale_ch.cloud.volume:
    uuid: "{{ my_ssd_volume.uuid }}"
    servers:
    - uuid: ea3b39a3-77a8-4d0b-881d-0bb00a1e7f48

by server name

- cloudscale_ch.cloud.volume:
    uuid: "{{ my_ssd_volume.uuid }}"
    servers:
    - name: my-server

Thanks for this suggestion, I created an issue. We will find more parameters which could take a name or an uuid and even an object: https://github.com/cloudscale-ch/ansible-collection-cloudscale/issues/56
