Add Support to Bypass Approval of Comments for Admins

[SudharakaP]

Describe the bug
Currently when a user posts a comment an admin has to approve it. This even applies to admins which doesn't make sense. We need to make sure when admins post a comment that is directly posted.

To Reproduce

1. Login as an Admin
2. Add a comment to a video

You will not see the comment posted right away. You will have to go into Entities -> Comments and approve your own comment.

Expected behavior
The comment should post right away for an Admin.
