User Story

As a user, I want an easy way to set verbosity on autoscaler so that I can debug my scaling issues.

Background

Currently verbosity can be set via the `CLUSTER_AUTOSCALER_VERBOSITY` environment variable. This is also documented here: https://access.redhat.com/solutions/6172162

However, the above method is only temporary and may be reset by the cluster-version-operator.

Steps

• Implement verbosity option in cluster-autoscaler-operator

Stakeholders

• Cloud team

Definition of Done

• Autoscaler CRD has verbosity option

• Docs

• Verbosity option needs to be documented

• Testing

• Create Autoscaler object with verbosity set to 2 and verify that autoscaler with correct verbosity is deployed.
