Ticket migrating to xblock.utils from xblockutils after deprecation of repo

[farhan]

Predecessor ticket: openedx/XBlock#675

The xblock-utils repo has been deprecated and in this story, we have to list down all the repositories that are using the xblock-utils package and switch the usage/import from xblock-utils to xblock.utils

Tasks:

• Go through all the repositories that install xblock-utils. For each repo that installs xblock-utils, open an issue for removing xblock-utils, like this one

Acceptance Criteria:

1. All repos that use xblock-utils have an issue indicating that they need to upgrade and migrate.

Package xblockutils has been found in following 17 repositories and issue has been created in all of these repositories:

@farhan, it would be great to keep the old imports as a fallback instead of breaking the backward compatibility of these 17 repos with all releases older than Quince (not released yet).

So add a try-except clause for the new imports and then try the old imports if we don't find the new ones?

[Agrendalath]

@feanil, exactly; something like this:

try:
    from xblock.utils.resources import ResourceLoader
    from xblock.utils.settings import ThemableXBlockMixin, XBlockWithSettingsMixin
except ModuleNotFoundError:  # For backward compatibility with releases older than Quince.
    from xblockutils.resources import ResourceLoader
    from xblockutils.settings import ThemableXBlockMixin, XBlockWithSettingsMixin
