Due to API Server restricting access to admin role user only, so below changes
are done as of now:
1. Restrict contrail-webui login only to admin user, user must have at least one
project access with admin role.
2. At login time set the cookies to the project which does have access with admin role.
3. Display only the project which the user has admin access in config pages.
4. Adding genBy as mainServer/jobServer to identify the request came from.
