Admin REST API to force switch topic Id

[gregscullard]

Is your feature request related to a problem? Please describe.
This api would force a restart of the applications (if running in docker-compose, it would automatically restart) so that a new topic id can be taken into account easily.

This should also delete all data in the database.

Describe the solution you'd like
Implement an admin rest API to "switch to new topic id"
Posts a message to the current topic containing new topicId
When message received, delete all data from database
Update topicId in .env
Exit the application which will restart automatically and pick up the new topic id if run in docker-compose.
