SEARCH-680: Index genre annotations

[reosarevok]

Implement SEARCH-680

AFAICT this is all that needs to be changed, except for generating new triggers and whatnot so that they check genre_annotation. But I didn't manage to generate them locally with the command in a8798bc - dunno if that's changed or something is missing here (it complains about ModuleNotFoundError: No module named 'sentry_sdk' but I also can't run setup properly, it seems, because then it complains about No such file or directory: 'mbrng/__init__.py). Maybe someone else can generate them and squash?

If you are using Local development of Search Index Rebuilder setup, then it is supposed to install requirements when starting the container, so just restarting the service indexer should do. If not, we would have to further investigate this issue.

I was just trying to run the script from a local clone of sir itself, nothing else :)

[yvanzo]

Have you reinstalled the requirements? Otherwise it might be a problem with your running environment.

[reosarevok]

I managed to generate these through the sir container :) So this should be fine, now, hopefully.

The code changes look good but I didn’t test it either.

The reindex couldn’t work because of a bug in the commit dff0a11 it was based on. A fix for this bug is in master but it depends on code migrated to SQLAlchemy 1.4 and which isn’t production-ready yet. So as a workaround, this pull request can be based on the temporary branch released-master (which match the latest release v3.0.1) until master gets stabilized.

I confirm that no change is required in any other repository to make it work as genre will only appear in annotation core’s type field in MB Solr schema which is a free string.

Rebased this, and added a test for genre annotations (which passes).
