Reused the output options and logging setup mix-ins.
Fixed a bug introduced in previous commit on `salt.utils.parsers.SaltCPOptionParser._mixin_after_parsed()`, function does not accept any arguments.
For this, the timeout mix-in and both the target and output parser group mix-ins were re-used. Way less code and logic to keep track of.
Added a simple test for this binary too.
* Created 2 mix-ins as option groups, the output options and the target options. This will allow adding some explanatory text besides separating these options from the parser's main options.
* All options on the parser, including the grouped options are now merged to the loaded configuration which will latter get passed on.
* Also created the timeout mix-in which will be used in other binaries.
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
