Get tests working the best I can with a stock Artifactory
Initial work on a System set of calls.
Adding tests, and fixing problems found by tests
Add updating the system configuration. Which required a post command in addition to the put command.
Just break apart test into multiple lines, which makes it easier to debug.
Standardize all REST calls through a central method, and remove custom methods like getSlurper.
Merging 3.0.2 changes
Cleanup and add contentLength arguments, though still not using them because upstream doesn't
Merge pull request #11 from quidryan/system-configuration

Add System configuration calls
