Move abilities by subject class to a dedicated method (EE)
What does this MR do?
Twin of gitlab-org/gitlab-ce!5668.
It moves the case
that returns abilities depending on the subject class to a dedicated method.
This should avoid lame conflicts when CE to EE since the EE version assign the result of the case
to a variable.
What are the relevant issue numbers?
Closes gitlab-org/gitlab-ce#20621.
