There's an inconsistency between chasquid (which uses `--config_dir`) and chasquid-util (which uses `--configdir`). That is prone to cause confusion, so this patch renames chasquid-util's flag, leaving the old one as deprecated with a warning message. Closes https://github.com/albertito/chasquid/pull/60. Amended-by: Alberto Bertogli <albertito@blitiri.com.ar> Added test case for the deprecated option, adjusted commit message.
