Subject: added FRG channels to slow channel ini file 

[Vacuum gauge sensors]

Paco informed me that the FRG sensor EPICS channels are not available on dataviewer, so I added them to slow channels ini file (/opt/rtcds/caltech/c1/chans/daq/C0EDCU.ini). I also commented out the old CC1, CC2, CC3 and CC4 gauges. A service restart is required for them to become available but this cannot be done right now because it would adversely affect the progress of the upgrade work. So this would be done at a later date.

Finally incorporated the FRGs into the main modbusIOC service and everything seems to be working fine. I have also removed the old sensors (CC1,CC2,CC3,CC4,PTP1,IG1) from the serial client list and their corresponding EPICS channels. Furthermore, the interlock service python script has been updated so that all occurrence of old sensors (turns out to be only CC1) were replaced by their corresponding new FRG sensor (FRG1) and a redundnacy was also enacted for P1a where the interlock condition is replicated with P1a being replaced with FRG1 because they both sense the main volume pressure.
