[RFE] test setup for plugins

[illume]

Current situation

Currently there is no test setup for plugins, so people have to do it themselves.

Impact

For people wanting to write tests it's easier if it's setup and working.

Ideal future situation

npm run test for plugins works.

Implementation options

Like with the tools create react app supplies.

• jest
• react testing library

Storybook is kind of related, maybe worth considering at the same time.

[illume]

Probably need a copy of Headlamp frontend/ code for this. (Either copied into headlamp-plugin or via a headlamp package.)

Because the tests run the code and therefore just supplying types are not sufficient.

This is done.
