#5 improve user role and site management

[thapacodes4u]

What was done in this PR?

Role create/edit:

• We already have site_id column in roles table. So add a site field in Create & Edit user page were user can select. (Completed)

User create/edit/view:

• Set user's global roles (when editing or creating user). (Completed)
  • Here I have added a way to identify Global or Site-specific role in the dropdown
• Set user's roles for each site. (Completed)
  • Here I have added a new multi-select field were you can select which site access you want to give to the particular user
• When saved, the site_has_user table should also be updated. (Completed)
• View user's global and site roles on the view page (only for sites the admin has access to). (Completed)
  • I have added a new secction called Access Information that basically provide info about what site they have access to and what roles they have.

User control:

• User can login only on his sites.
  • This was already applied. Don't know if you mean any specific implementation here.
• New users must get the panel_user role, no matter where they came from (registration, seeder...)

Site management:

• When a new site is created, all users with global roles should be added to it, so they have the role on the new site also
  • I assumed global role means those whose site_id is null. So anyone having this role should have access to any new site that gets created.

User list:

• By default, the users list should display only users for the current site
• Add columns for user's global and (current) site roles
• A filter can be set to see users from all sites (that the admin has the access to)
• A filter for global and site roles (any role/specific role)
