Use a nicer reload method on hot schema update
...
Instead of exiting and trusting systemd to restart us, instead leverage
the os.execv() call to reload the process in the current PID context.
Also improves the log messages so it's very clear what's going on.

Handle hot reloads properly
...
A hot reload isn't possible due to DataWatch and ChildrenWatch
constructs, so we instead need to terminate the daemon to "apply" the
schema update. Thus we use exit code 150 (Application defined in LSB)
and reorder some of the elements of the schema validation to ensure
things happen in the right order.

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.
