What is the nature and description of the request?
Currently AAP git project synchronization is performed from one controller.
Add an option from the project to force the project synchronization on all controllers.

Why does the customer need this?
Users can't be certain that the project is synchronized on all controllers and so this can lead to unexpected behaviors.
For example, a user can launch a project synchronization that is successfull and later have random jobs failing because in the meantime the git token expired and the project sync only was perfomed on one controller.

How would you like to achieve this?
Add a new API project parameter (such as "scm_clean", "scm_delete_on_update", "scm_update_on_launch", etc) and add a new web UI checkbox (such as "Clean, "Delete", "Update Revision on Launch", etc).

List any affected known dependencies: 
Controller API, Controller Web UI, Project updates playbooks.
