This option determines whether Patrole should run against a
`custom_requirements_file` which defines RBAC requirements. The
purpose of setting this flag to True is to verify that RBAC policy
is in accordance to requirements. The idea is that the
`custom_requirements_file` perfectly defines what the RBAC requirements are.

Here are the possible outcomes when running the Patrole tests against
a `custom_requirements_file`:

YAML definition: allowed
test run: allowed
test result: pass

YAML definition: allowed
test run: not allowed
test result: fail (under-permission)

YAML definition: not allowed
