Extend collection requirements

[felixfontein]

Based on the discussion in today's community meeting.

[felixfontein]

• The ansible package MUST NOT depend on collections not shipped in the package.
• If you plan to split up your collection, the new collection must be approved for inclusion before the smaller collections replace the larger in ansible.
• If you plan to add other collections as dependencies, they must run through the formal application process.

[felixfontein]

Agreed in the community meeting to merge this.
