LGTM
@agrare who would be the relevant reviewer/merger from core?

[karelhala]

@abonas well it does not technically add it there, it just enables ui-classic to add it. I'll reword the description so it address it correctly.

@aljesusg please review

[martinpovolny]

@karelhala : you should also add the permission to the relevant pre-defined roles in db/fixtures/miq_user_roles.yml

[karelhala]

@martinpovolny all done.
@abonas I have added option to check for compliance to all predefined roles, is that ok?
