Description of problem:

The default in ACM for the root disk size is 128GB but after installing the cluster, RH Insights alerts that the size should be 1024GB per recommendations.

Version-Release number of selected component (if applicable):

OCP 4.17.12
ACM 2.12.2

How reproducible:

Always

Steps to Reproduce:

1. Create a new Azure cluster in ACM web interface
2. Use defaults that are given in the GUI
3. Install cluster
4. Wait for Insights to run (maybe requires ~24 hours?)
5. Insights alert should fire on managed cluster

Expected results:

When using defaults, it is reasonable to expect that the cluster that is created is within the recommended parameters

Additional info:

Insights rule is called ccx_rules_ocp.external.rules.disk_low_throughput_in_azure
