Make enterprise removal use turbo, which provides the following
benefits:
* More responsive removal since there's no full page reload.
* A success flash message (previously nothing was displayed).
* No double alert prompt.
It also goes in the direction of removing mrujs in favor of turbo.
Enterprises are stored in `@enterprise_set` variables, and we iterate over to show the list of enterprises to super admin.
Previously, we used to use `Sets::EnterpriseSet.new(collection)` instead of creating set based on `@collection`: this leads to call the `collection` method twice, which was probably very time consuming. This commit fix also that.
+ use paginated enterprises loading on bulk update but without testing if the current user is an admin
