In the past the master has been taking the kwargs passed in and converting them to a string (kwy=value) and letting the minion de-yaml that arg string. In general this is okay, but it doesn't work well if you are calling from the python LocalClient interface-- since the kwarg you passed already had a type. With this change instead of converting the kwarg to a string it is converted to a dict with a flag to mark it as a kwarg dict, then it is unpacked on the minion side while still maintining type
In addition to traditional file system path test discovery it is
useful to run a test by stating it's dotted python path. For example,
this will only run the cmdmod integration tests from the
module suite::
$ runtests.py -n tests.integration.modules.cmdmod
