HWS camera control shows running status

Tuesday morning I found that HWS ETMY camera control had stopped running at 06:27 PDT for unknown reasons. This was discovered when H1 went out of lock at the start of maintenance and the ETMY camera was not enabled. This was not an actual issue because the ETMY camera is turned off.

To bring attention if a camera controler stops running I made two changes the camera control system:

1) Added GPS times to the controller code (required loading python3-requests and python3-dateutil for gpstime)

2) Added run-status widgets to MEDM, if a camera controller's GPS falls behind by 5 minutes or more its MEDM shows a purple block

Attachment shows ETMY in a stopped state.
