User type switching from the profile section

[harshtalati2410]

Add a "Change Role" dropdown at the bottom of the sidebar. This dropdown should contain the list of all possible user types(i.e., student, faculty, recruiter, Admin, TPC Manager). It should show the current role of the user.
On clicking a role apart from the currently active role, the user containing the role stored as a cookie is changed accordingly and the page is refreshed to display UI changes accordingly.
