VACSTAT: gauges in vent area removed from system

Janos, Gerardo, Dave:

Following some alarms overnight we have decided to remove the LVEA gauges from VACSTAT for the duration of the vent. The other gauges which will remain under vacuum continue to be monitored, but without the increased sensitivity settings.

In order to keep the EDC green, a vacstat_dummy_ioc.py is running on opslogin0 to simulate the channels associated with the removed gauges (HAM1, HAM6, BSC2, BSC3).

The cell phone alarms to the vacuum group on multiple vacstat detections has also been disabled.
