Add a logging.info mode to chpl_launchcmd.py

[reviewed by @e-kayrakli]

–CHPL_LAUNCHCMD_DEBUG is helpful for figuring out what launchcmd is
doing when you need to debug, but it ends up being really verbose and
hard to sift through. Add a --CHPL_LAUNCHCMD_INFO mode that displays
more limited information.
