Market:

Autoscaling in OSP consisted of 4 components up to OSP 17.1

ceilometer for data gathering
gnocchi to store and provide metrics
aodh as alarming component that would
- store alarming rules
- iterate over the rules
- evaluate the rules, fetch the metrics from the data store
- compare and if necessary: fire up an action
heat to orchestrate the changes triggered by the alarm action

This is a dependency for OSP-23207; either we can deploy gnocchi, or change aodh so that e.g prometheus can satisfy this dependency.
