Add app_log_revision property (#442)

This new property enables app logs in the format APP/REV/<version>/PROC/WEB/<process>.

We added this property to the following jobs:
* cloud_controller_ng
* cc_deployment_updater
* cloud_controller_clock
* cloud_controller_worker

We believe cloud_controller_worker does not send desired_lrp actions to diego, however
we were not completely sure so we added it just incase.
