Adds filter on the front end for users

[mpgxvii]

• Adds filter on the front end to hide rest source user data from users who do not have the correct permissions from management portal (uses management portal assigned projects)
• I guess this would be better implemented on the back end?

Partially solves #13

hi @mpgxvii , I think yes this needs to be done from the backend based on the token provided by the frontend. The frontend should only be responsible for getting a valid token using auth code flow.

@yatharthranjan Also, I was wondering maybe it would be good to implement this similar to Management Portal front end? Where projects (where the user has access to) are shown upon login?
