Joshua Boniface b6474198a4 Implement cluster maintenance mode 
Implements a "maintenance mode" for PVC clusters. For now, the only
thing this mode does is disable node fencing while the state is true.
This allows the administrator to tell PVC that network connectivity,
etc. might be interrupted and to avoid fencing nodes.

Closes #70

Joshua Boniface 7b3e267f7a Implement bridge_device for bridged VNIs 
Required due to #64. Bridged networks were being created on top of a
vLAN if the Cluster network was a vLAN device, rather than being created
on the underlying device. This came from a previous revision of the
cluster architecture guidelines where Cluster was supposed to be a raw
device rather than a vLAN. This fixed the problem by implementing a
configuration field for a "bridge_device", a NIC device that can then
have the bridged vLANs created on top of it.

Fixes #64

Joshua Boniface 4249d5d982 Always load and store IPMI on daemon start 
Without this, the IPMI information set during initial node creation can
never be changed, which can cause issues later. Instead, always set it
fresh on each node boot.

Joshua Boniface 0d398f663b Rename "Domain" to "VM" in various class names 
The name "Domain", though technically correct from a Libvirt
perspective, was unnecessarily confusing. Call the class instances what
they are, VMs.

Joshua Boniface 8216125b02 Enable autostart of API client on Primary 
Adds a config flag that turns on the API client following the Primary
coordinator. The retcode of the start/stop commands is ignore so this
can fail gracefully if e.g. the client isn't installed.

Joshua Boniface 75d0e7f989 Revert "Only perform fencing duties on primary" 
This reverts commit 464c69aac6.

Actually, yea, this made sense - if the primary fails, it can't
fence itself.

Joshua Boniface 464c69aac6 Only perform fencing duties on primary 
There was really no need for this to be shared among all the
coordinators, which seemed more fragile. This way only the primary will
try to fence dead nodes.

Joshua Boniface 0060c0313b Put daemonstate to shutdown when stopping 
This way it isn't "run" all the way until it shuts down.

Joshua Boniface db0b382b3d Don't bother with snapshot management by Daemon 
This is *definitely* not needed in the end, and just uses RAM for
no conceivable purpose. Snapshots are fully client-managed.

Joshua Boniface 1c9f606480 Implement volume and snapshot handling by daemon 
This seems like a super-gross way to do this, but at the moment
I don't have a better way. Maybe just remove this component since
none of the volume/snapshot stuff is dynamic; will see as this
progresses.
