grafana role changes monitoring stack config if user workload monitoring was not enabled

[witekwww]

Collection version

22.5.2

Environment information

quay.io/ibmmas/cli 10.9.2

What happened?

When installing MAS Core using oneclick playbook the grafana role is run. This role checks if there is user workload monitoring enabled. If not it changes the cluster-monitoring-config ConfigMap. The role does not append the 'enableUserWorkload: true' but removes all the config that was in the configmap before. It should only append the necessary entry and not remove all previous configuration.

Relevant log output

no log available.
The code responsible for the bug is this (ibm/mas_devops/roles/grafana/tasks/install/main.yml, lines 11-23):

- name: "install : Configure User Workload Monitoring"
  when: uwm_secret_lookup.resources | length == 0
  kubernetes.core.k8s:
