Joshua Boniface 323c7c41ae Implement node logging into Zookeeper
Adds the ability to send node daemon logs to Zookeeper to facilitate a
command like "pvc node log", similar to "pvc vm log". Each node stores
its logs in a separate tree under "/logs" which can then be combined or
queried. By default, set by config, only 2000 lines are kept.

Joshua Boniface 9ea9ac3b8a Revamp tag handling and display
Add an additional protected class, limit manipulation to one at a time,
and ensure future flexibility. Also makes display consistent with other
VM elements.

daemon.

Joshua Boniface 64d1a37b3c Add PCIe device paths to SR-IOV VF information
This will be used when adding VM network interfaces of type hostdev.

Joshua Boniface e7b6a3eac1 Implement SR-IOV PF and VF instances
Adds support for the node daemon managing SR-IOV PF and VF instances.

PFs are added to Zookeeper automatically based on the config at startup
during network configuration, and are otherwise completely static. PFs
are automatically removed from Zookeeper, along with all coresponding
VFs, should the PF phy device be removed from the configuration.

VFs are configured based on the (autocreated) VFs of each PF device,
added to Zookeeper, and then a new class instance, SRIOVVFInstance, is
used to watch them for configuration changes. This will enable the
runtime management of VF settings by the API. The set of keys ensures
that both configuration and details of the NIC can be tracked.

Most keys are self-explanatory, especially for PFs and the basic keys
for VFs. The configuration tree is also self-explanatory, being based
entirely on the options available in the `ip link set {dev} vf` command.

Two additional keys are also present: `used` and `used_by`, which will
be able to track the (boolean) state of usage, as well as the VM that
uses a given VIF. Since the VM side implementation will support both
macvtap and direct "hostdev" assignments, this will ensure that this
state can be tracked on both the VF and the VM side.

Joshua Boniface f030ed974c Correct schema and handling of network subkeys
Required a bit of refactoring in the validation code to ensure we have
direct access, without relying on the translations done in the normal
zkhandler functions.

Removes a superfluous lock and puts the sync_lock keys in more usable
places.

Joshua Boniface 3c102b3769 Add per-node schema tracking
This will allow nodes to start with their own schema versions, and then
be updated simultaneously by the API.

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.
