Ryan Kraus 106c53abf1 Revised HASS Core test
Changed the HASS Core test that tested KeyboardInterrupt handling to
now test SIGTERM handling. KeyboardInterrupts are no longer handled in
the HASS application process as they are handled in the HASS parent
process. SIGTERM is the proper way to now stop HASS.
