14066 extensibility add coretriggerroute table (#14241)

This Pr 
- adds a `route` table to the core schema
- adds a controller to trigger route

For now, we need to add a `/s/<workspace_id>` prefix to all routes

We plan to create a custom domain table in order to let the users create
subdomains for their workspace, and so to link their routes to a
subdomain. Thank to that, we will be able to identify workspace_id from
domain name, and the prefix could be `/s`. If we create a native
dedicated subdomain for routes for each workspaces, the prefix could be
completely removed!

Here the follow up ticket to do that ->
