Several files in the REST APIs nav section are included using
:leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.)
in those files and removes the :leveloffset: tags.
Other supporting changes:
* Alphabetizes top-level REST API nav items.
* Change 'indices APIs' heading to 'index APIs.'
* Changes 'Snapshot lifecycle management' heading to sentence case.
This commit adds multiple repositories support to get snapshots
request.
If some repository throws an exception this method does not fail fast
instead, it returns results for all repositories.
This PR is opened in favour of #41799, because we decided to change
the response format in a non-BwC manner. It makes sense to read a
discussion of the aforementioned PR.
This is the continuation of work done here #15151.
