    azure_rm_loganalyticsworkspace:
        resource_group: "{{ main_resource_group }}"
        name: "{{ npe_loganalyticsworkspace_name }}"
        intelligence_pack:
            Backup: true
            Containers: true
        profile: "{{ profilename }}"

```


##### EXPECTED RESULTS
I assume it creates workspace with those features enabled 


##### ACTUAL RESULTS
