[1LP][RFR] Add subscribtion test blocker.

[jarovo]

Adds blocker for ManageIQ/manageiq#20390
{{ py.test: -sv 'cfme/tests/configure/test_register_appliance.py::test_rh_registration' --long-running --use-provider 'complete' }}

[mshriver]

Why not include this in the meta blockers?

This needs to be skipped/blocked like this:

integration_tests/cfme/tests/networks/test_provision_to_virtual_network.py

Line 44 in 55a9d4a

GH('ManageIQ/integration_tests:8128'),

[jarovo]

@mshriver If you mean to use GH('ManageIQ/manageiq:20390') then I believe those approaches are equivalent.

Looking at the results I see the skip did work fine. The failed test_rh_updates is not related to this PR.

[mshriver]

Need to use blockers meta marker for GH or BZ skipping.

[jawatts]

@JaryN we have the marker to to have consistency across the framework.

[mshriver]

Please use the existing meta marker and include the blockers kwarg, as it supports GH issues.

[jarovo]

@mshriver Thanks. I planned to make the skip conditional and forgot about that. However, with the current configuration it blocks all the tests anyway.

[mshriver]

Please use the meta blockers kwarg instead of skipping within the pytest run phase.
