Ability to disable the personal spaces creation automatically

Issue Summary

When invited to a Confluence Cloud instance, users have a personal space created automatically (either through the onboarding or due to the feature that automatically creates it for the users).

This, sometimes, can clog up the instance and it would be useful to have an option to disable it on a site level instead of disabling the creation of personal space for each group having access to Confluence.

Workaround

You can disable Personal Space permissions for user groups in Global Permissions. However, users will not be able to create their personal space manually.
