Allow non-Enterprise administrators to control managed users' associated sites and products

Update added 17 November 2023

I'm updating this ticket to reflect the October 6 changes outlined in this ticket: ACCESS-1468 – Allow Administrators to control managed users' associated sites and products

As an administrator, I would like to have the ability to control and configure permissions to my organization's managed accounts, these permissions are:

• Ability to create new sites for Jira, Confluence, JSD
• Ability to create new Bitbucket or Trello accounts
• Ability to join sites or products external to the organization
• Ability to remove managed users from external sites
• Ability to remove access to specific products

Original summary and description

"Prevent users under a verified domain for being able to sign up for a new Cloud instance"

Not allow users of a Cloud instance which has the domain already claimed for being able to use their email(verified domain) for sign up to a new Atlassian Cloud instance.

If some user wants to get a new Cloud instance for any reason, it should ask for the instance Administrator.
