* A per-repo lock mechanism.
*
* This ensures that project creation (repo creation, config creation, first commit) is atomic,
* and can be used to separate creation and deletion in the delete-project plugin.
*
*
This is an interface because distributed setup may need something beyond an in-memory lock.
