Show "Is Using License Seat" labels in Members tables
Problem to solve
This issue has the same problem of https://gitlab.com/gitlab-org/gitlab-ee/issues/6995, it focuses on addressing it for GiLlab.com
Proposal
- If I'm an Owner in the namespace, I should be able to see the "Is Using License Seat" label.
- This label should only surface if that user is using a seat for that GitLab.com namespace.
