  init: Decrease verbosity of --exec (#2457)

* If --exec or -e (exit with -c) is used, do not show the 'Starting' message. Only one operation will happen, so no need to emphasize there is a session starting.
* Do not show 'Creating' message for --tmp-location. It is temporary, no need to know it is being created when that's what was requested and it will be deleted at the end.
* Show 'Executing' and 'Execution...finished' messages only in verbose mode. By default, there is no need to echo the command which was received.
* Clarify interface of run_batch_job and fix its documentation. Remove unused env var related code.
