This PR existed for some time.
It was originally created for documenting families_transfer attribute OP-8268
Personally, we can't document an attribute in a section without documenting the whole section therefore, I stretched the scope of this PR a little bit.

This PR still lacks some definitions for the Process submitted job on farm plugin settings

[MustafaJafar]

I've update this PR. and I think it's ready to merge.
Feel free to review and ensure the documentation communicates well.

I tried to clean up a bit chunk size issue in ynput/ayon-deadline#33 , so documentation might need to clean it up too.

[MustafaJafar]

I've update the PR in compliance with ynput/ayon-deadline#33
Also, added missing definitions for settings.

Looks good to me - just one small comment.
