⚡ Reimplement connector management

[tjarbo]

As a User
I want create, delete and edit new connectors right from the web-interface
so that I can manage e.g multiple discord channels

Description:

With #119 it's not possible anymore to edit the connectors. With this user story epic it is time to redesign the API to allow CRUD operations on connectors now. The draft is:

• GET /api/connectors to get a list of all connectors ✨ Get list of all connectors #144
• POST /api/connectors to register a new connector ✨ Add new connector #151
• [ ] GET /api/connectors/:id to get information about connector Not needed right know
• PATCH /api/connectors/:id to update a connector ✨ Update a connector #145
• DELETE /api/connectors/:id to delete a give connector ✨ Delete a connector #146
• GET /api/connectors/:id/logs to receive latest logs from connector #171

Checklist:

• Re-implement API with the given endpoints
• Delete old unused endpoints
• Update documentation
• Rename bots to connectors @ frontend

This user story is to much for one story -> new tickets will be created

This issue will be closed, because #171 is its own user story and with #200 finally the documentation is on the newest version.
