Create Che Plugin Registry starter

[mmorhun]

Is your task related to a problem? Please describe.

Official Che Plugin Registry code is located here. When a user wants to have own registry it requires forking of existing official registry and changing its content (by removing many plugin entries, maybe removing git histiry, etc.) or create the scaffold manually. Such approach is not user friendly, so we need to improve the flow.

Describe the solution you'd like

We should have some generator or registry template to make it easy to users to create and host own Che plugin registry. So a user could just fill in information about plugins (write meta.yaml) and put it in appropriate folder(s). Then run a script which should update index file of the registry, optionally create docker image, etc.

@mmorhun would be super cool to have Hosted Che as a default dev environment for such a starter

This is a nice idea, once we have better support for multiple plugin registries it seems doable.
