[CIS Azure] 2.1.* rules require subscription to Microsoft.Security in order to pull evaluation data

**Describe the bug**
There is a requirement from Azure to enroll into the `Microsoft.Security` in order to pull the data that we need for `2.1.*` rules evaluation.

This affects pulling of the following resources:
- `microsoft.security/autoprovisioningsettings`
- `microsoft.security/securitycontacts`

Due to that users that aren't enrolled won't be able to get evaluations for `2.1.*` rules.

**Expected behavior**
We should investigate and try to figure out how to evaluate these rules without any enrollment from the user.
If there is no option to evaluate these rules without the enrollment, then we need to document that and reflect to the customer.

Definition of done
- [ ] Look for a different way to pool the relevant data for evaluation
- [ ] Document enrollment to Microsoft Security as a prerequisite
