Subject: [PATCH] Feature/rt automation (#403)

* rt automation script
* rt automation script w/o token
* getting machine name test
* Updates to python script, and addition of YAML database
* added check for approved users, added check for triggers in pr comments
* Script now interacts with github directly, is able to process triggers
* Added threaded process submition with callback for regression tests
* remove an extra sys.exit()
* Switched to using Labels
* Rename RegressionTests_hera.intel.log to RegressionTests_neon.intel.log temp change to test function
* Rename RegressionTests_neon.intel.log to RegressionTests_hera.intel.log reverted
* AUTO: Updated tests log
