    phase1: AnyBranchScheduler: make treeStableTimer configurable
    
    The AnyBranchScheduler will currently wait for 15 minutes before
    starting a build.  If new changes are made on the same branch during
    this interval, the timer will be restarted.
    
    For staging repository we want faster feedback loop, so we're going to
    use much lower value, thus lets make this configurable and handled via
    Ansible.
