Joshua Boniface 126f0742cd Add Zookeeper schema manager to zkhandler 
Adds a new class, ZKSchema, to handle schema management in Zookeeper in
an automated and consistent way. This should solve several issues:

1. Pain in managing changes to ZK keys
2. Pain in handling those changes during live upgrades
3. Simplifying the codebase to remove hardcoded ZK paths

The current master schema for PVC 0.9.19 is committed as version 0.

Joshua Boniface cd75413667 Increase initial lock timer 
With the new library the reader seems to be a little too quick, so hold
the write lock for 1 second instead of 1/2 second to ensure it is
caught.

Joshua Boniface b851a6209c Catch all other exceptions in subprocess run

a daemon crash. Catch these exceptions with a retcode of 255 instead of
bailing out.

Closes #124

Joshua Boniface 5ceb57e540 Handle emptying corrupted console log files 
Libvirt will someones write junk out to console log files, which breaks
the log parser deque with a UnicodeDecodeError.

If this happens, clear the log and re-open the deque again for newer
updates.

Joshua Boniface aba567d6c9 Add nice startup banners to both daemons 
Add nicer easy-to-find (yay ASCII art) banners for the startup printouts
of both the node and API daemons. Also adds the safe loader to pvcnoded
to prevent hassle messages and a version string in the API daemon file.

Joshua Boniface a44f134230 Remove systemd deps on zookeeper and libvirt 
This caused a serious race condition, since the IPs managed by PVC had
not yet come up, but Zookeeper was trying to start and bind to them,
which of course failed.

Remove these dependencies entirely - the daemon itself starts these
services during initialization and they do not need to be started by
systemd first.

VMs.
