Adding more performance metrics

* Implemented CLTuning flow for ExecuteNetwork tests
  * Added --tuning-path to specify tuning file to use/create
  * Added --tuning-level to specify tuning level to use as well as enable extra tuning run to generate the tuning file
* Fixed issue where TuningLevel was being parsed incorrectly
* Added measurements for initialization, network parsing, network optimization, tuning, and shutdown
* Added flag to control number of iterations inference is run for
