Running SoapUI Project Test Suites in Parallel through CLI command run (TestRunner.bat)

Ability to run SoapUI Pro project in parallel from command line. 

In our execution log, it says following (RunType=Sequential)  - We want to have RunType=Parallel

21:04:36,105 INFO  [SoapUIProTestCaseRunner] Running Project [Card-Requirement], runType = SEQUENTIAL

This is high priority for us because our test cases are getting large and taking too long to execute on Jenkins master/slave configurations. and also directly impacting our sprint schedule velocity. We need to speed up test case execution from CI automation system
