Goal:

The current code: https://opendev.org/openstack/python-observabilityclient/src/branch/master/observabilityclient/v1/rbac.py

• The code needs to be made usable from outside of the observabilityclient (we will need to import it from aodh, from aetos and possibly from other services as well).
• We need to ensure the code works really well, as it'll be an essential part of the multitenancy feature. We can include testcases from the prom-label-proxy to expand our testing https://github.com/prometheus-community/prom-label-proxy/blob/main/injectproxy/enforce_test.go
• PromQL docs
  • https://prometheus.io/docs/prometheus/latest/querying/basics/
  • https://prometheus.io/docs/concepts/data_model/

Acceptance Criteria:

• PromQL modification can be used from outside observabilityclient
• PromQL modification code is well tested
