Save site admin's user role as an option in newly created site.

As an example use case this can be used to create specific user plans by a Hosting provider such as Plan1, Plan2, Plan3 assigned to the user on the main site. This information can be stored on those newly created sites along with Site Type which can be Personal, Business, Enterprise, etc.

We can then create a batch of Plugins/Themes to be displayed to the site administrators based on their user role saved on the particular site. This will be like giving users Plugins/Themes based on their Plan selected. This can then be tied with an automated system which changes a user role to update this option for sites they own, etc.
