Create a list of privileges for TAs

[Jnxiong04]

• We would like to create of list containing all of the privileges a TA will have on NodeBB, which are: make a post, reply to one, quote, upvote, can only delete/edit their own post, select who can see their posts (all, instructors only). This makes it so that it would be easier to check whether or not a TA has permission to complete an action, see private posts, “good note!” endorsement
• This is a low effort task
• There are no dependencies for this task
• Acceptance Criteria: A list of privileges has been created with each element in the list being a 0 if the student does not have the privilege or a 1 if the TA does. This list should be attached to each TA.
