DAQ and EDC restart, new CS HepiPumpCtrl channels, removed h1susbs FEC, removed end station DUST VEA2

Jonathan, Patrick, Erik, Dave:

We restarted the DAQ + EDC around 16:00 this afternoon primarily to install Patrick's new H1EPICS_HEPIPUMPL0.ini to match his new IOC.

At the same time we removed the end station VEA2 Dust monitor channels, there hasn't been a second dust monitor at the ends for some time and the Sat power outage required an EY Dust restart which removed its VEA2 channels from the ioc. We also made the EX INI change for when its IOC is restarted.

To green up the EDC, we temporarily removed h1susbs' FEC-31 channels. Erik has put H1EPICS_[FEC,SDF].ini under puppet control, so these will be added back when h1susbs is reinstalled.

We also fixed an issue whereby yesterday puppet added some incorrect KC0 channels to the EDC. This was fixed today and there are now no KC0 channel in H1EPICS_DAQ.ini, they all reside in the hand-built H1EPICS_DAQKC0.ini. Around today's restart time KC0 coincidently went unstable, restarting itself every 5 seconds. The problem was downstream of KC0. Jonathan contacted LDAS and the problem was fixed within the hour.

The EDC is green again, first time since the power outage.
