Mark MultiRule as deprecated

[marschwar]

This is the first step in removing MultiRule. It closes #4240.

I will create a checklist (or separate issues) for all remaining steps.

Note: I changed the usages to fully qualified as the build was failing with deprecation warnings in the imports and I did not want to suppress deprecation warnings for the entire file.

Is this intended that we want to use the full qualified name for MultiRule?

[marschwar]

Is there any other way (besides suppressing deprecation warning for the entire file) to avoid the build to fail because of a deprecated import?

[BraisGabin]

There is not as far as I know. It would be really good to know if there is any other way.

You have a couple of references inside RuleProviderSpec which should also be annotated
