CMP-2400: exclusion of the namespace for rule ocp4-resource-requests-…

…quota-per-project

Excluded RHACS from the default namespace check. We don't want to releax our rule too much for optional operator,
as it might incress security risk, instead user should use tailoredprofile to set the exclusion regex.

Added a new variable 'var_resource_requests_quota_per_project_exempt_regex'
