docker: add debug image per release and edge tag

[nitisht]

Currently we use the Distroless base images (https://github.com/GoogleContainerTools/distroless) which offers great security and production readiness with its small surface area. But this also means there are no debug / troubleshooting tools available in the Parseable image which might be a problem for our users.

We need to create debug image tags for each release and edge image from now onwards. This way users can simply switch to the debug image for their tests and switch back to actual images once they are satisfied.

Also add Pyroscope integration for debug builds https://pyroscope.io/docs/rust/

Env vars

P_DEBUG_PYROSCOPE_URL

Add two API endpoints (only available in debug builds)

/api/v1/profile/start
/api/v1/profile/stop
