Fix codeowners file

Earlier cephci-top-reviewers had open permissions to merge code
to any place. The teams mentioned for folders had no impact. This
caused improper delegation of ownership.

This change removes the top-reviewers group and sets the complete
privileges to ceph-qe-ci and ceph-qe-admin groups. They have full
access to merge.

The delegation to each DFG is now done via specfic users with their
managers having permissions to merge in their respective components.

Going forward, anyone should be able to raise a PR to request for
merge permissions with admin and ci teams having approval privileges.
