Starting tomorrow I'm off until September, so you'll need to coordinate with @simskij and @sed-i on how to handle this, probably you should synchronize with this, prometheus and traefik else the cos-lite edge deployment will be briefly degraded (but hopefully it won't explode)

holding off the merge for now given the above

I'm having trouble packing the charm on this branch. I get this error:

ERROR: Double requirement given: opentelemetry-exporter-otlp-proto-grpc (from -r requirements.txt (line 10)) (already in opentelemetry-exporter-otlp-proto-grpc==1.17.0, name='opentelemetry-exporter-otlp-proto-grpc')

I checked the requirements files, but to me it doesn't seem like there are multiple imports.

Anyone else has issues like this?
