Ability to sync users to sites based on the groups

At this moment, user provisioning sync all the users and groups to all the sites below the hierarchy in the Atlassian organization where it is setup.

This suggestion is to add flexibility and make it possible to configure which users and groups you want to be mapped to specific sites instead of having all to all mapping.

Example of scenario:
A company has an organization with multiple sites and want each of them to have only a subset of the user provisioned users and groups being synced into each site.
