Get Test Args

Extracts the test arguments from the System Args

usage:
  python3 <test> -- -c /tmp/config.yaml --test_args=k1=v1 --test_args=k2=v2

CATBox usage:
  catbox-tradefed run commandAndExit <test-plan> --mobly-options --test_args=k1=v1 --mobly-options --test_args=k2=v2

Returns: Dictionary with key-value pair
  e.g.
