chore: add enterprise extension point to enable change requests on pr…

…oject creation (#6881)

This PR adds an optional function parameter to the `createProject`
function that is intended to enable change requests for the newly
created project.

The assumption is that all the logic within will be decided in the
enterprise impl. The only thing we want to verify here is that it is
called after the project has been created.
