cell phone alarms reconfigured, removed CP4 discharge line channels, changed PT245 alarm level

WP7357

Chandra, Dave:

The cell phone alarms configuration was modified in order to:

remove CP4 discharge line pressure channel (and associated error channel)

decrease CP4 vacuum gauge upper alarm level from 5.0e-04 to 5.0-e06 Torr

I also took the opportunity to make some code changes related to running the code in the background under systemd control. The STDOUT verbose reporting is now directed to a time-stamped file. Issuing a SIGUSR1 signal to the code will cause it to open a new reporting file, permitting me to rotate these files and compress the old ones (yes, I know python has logging with rotation, I'm using that to write low level logging output already).

Configuration change for PT245:

    H0:VAC-MY_Y4_PT245B_PRESS_TORR           VE gauge, MY CP4, CC  9.713e-07   True      0      0       OK    NO_ALARM   1.000e-10  5.000e-06

This should be a good configuration for the long weekend and maybe through next week.
