Description

Support for different plugins is added through the endpoints.
All endpoints are always loaded, which basically means that all the supported plugins have to be installed.

If one of the supported plugins is not installed, workers won't be able to start:

Proposed solution

E.g. If it's possible to import from the pulp3 plugin module, then load the corresponding endpoint, otherwise skip it.
