Docs:Redirects

New redirects: How to handle each case?

1. redirect-only inside the same collection (aka, permanaent alias).
   • [thoughts]
2. redirect-only to a different collection.
   • [thoughts]
3. deprecation with no redirect.
   • needs no special logic, since it is already handled by the regular docs build (ansible-test sanity ensures that runtime.yml deprecations agree with in-module deprecations)
4. deprecation and redirect inside the same collection.

5. deprecation and redirect to a different collection.

Existing redirects

Problem regex

Proposed fix:

• Remove the redirect. We don't need it anymore (affects 2.4 and 2.3-style URLs coming into the modern era)
• Replace with: RedirectMatch permanent "^/ansible/(devel|latest)/([^/]+_module).html$" "/ansible/$1/modules/$2.html"
