Allow event-routing-backends to be used when transforming non-openedx events

pomegranited commented 3 months ago

Description:

Event Routing Backends is designed to be installed with edx-platform, and the code assumes this. But we want to use ERB outside of the platform too -- it contains event transform classes and test logic which is useful when transforming non-openedx events.

This PR:

Catches ImportErrors from edx-platform to fix errors like these
Adds a utility function to add custom events to the backend whitelists.
Refactors transformer test mixin classes to make them available for use outside of ERB.

See https://github.com/open-craft/openedx-completion-aggregator/pull/205 for an example usage.
