Redo "Import abstract base classes from collection.abc in python 3.3+"

[sblaisot]

What does this PR do?

This PR reintroduces #54309

Starting from Python 3.3 abstract base classes from collections was moved to collections.abc. For backward compatibility those classes can be imported from collections directly. Since Python 3.7, importing abstract base classes from collections directly leads to this warning:

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working

This PR moves imports of abstract base classes from collections to collections.abc in compatible versions of Python (with a falback to importing from collections).

What issues does this PR fix or reference?

This PR fixes #52120

This has been previously fixed in #49487 but it seems the fix was incomplete.

Commits signed with GPG?

No

@sblaisot We are no longer accepting PRs to the develop branch. This needs to be re-opened against the master branch. You can link to this PR from the new one to preserve any disscussion history. Sorry for the confusion.

I just also wanted to say that closing PR due to a branch policy change on your side instead of changing target branch of the PR is a bit frustrating for external contributors who just want to help.

Nevermind, PR reopened against master as #55900
