User can view/edit Physician records in the Admin view

[francisli]

Let's create a new menu option "Physicians" in the Management menu for admins (route path = "/physicians"). Let's re-use the DataTable component to display a paginated list similar to Members and Patients that fetches and displays Physician records.

On selecting a Physician, let's go to a page where its full record can be viewed (route path = "/physicians/:physicianId").

The page should display an "Edit" button that will go to a form for editing (route path = "/physicians/:physicianId/edit").
