Add support for testing extensions

[nscuro]

Description

Allows extensions to provide functionality that lets administrators verify whether a given configuration is likely to work.

The primary use case here being a "test" button in the UI.

Having an easy way to test configuration provides much better UX, as the lack of feedback without it can cause a lot of frustration. Especially when the to-be-configured functionality only runs on schedule and can't be triggered manually at all.
