Joshua Boniface 6fa828e721 Don't stop the provisioner worker 
It should probably just be running on all nodes all the time already,
but is started when a node first becomes primary.

Joshua Boniface 5995353597 Implement VM metadata and use it 
Implements the storing of three VM metadata attributes:
1. Node limits - allows specifying a list of hosts on which the VM must
run. This limit influences the migration behaviour of VMs.
2. Per-VM node selectors - allows each VM to have its migration
autoselection method specified, to automatically allow different methods
per VM based on the administrator's preferences.
3. VM autorestart - allows a VM to be automatically restarted from a
stopped state, presumably due to a failure to find a target node (either
due to limits or otherwise) during a flush/fence recovery, on the next
node unflush/ready state of its home hypervisor. Useful mostly in
conjunction with limits to ensure that VMs which were shut down due to
there being no valid migration targets are started back up when their
node becomes ready again.

Includes the full client interaction with these metadata options,
including printing, as well as defining a new function to modify this
metadata. For the CLI it is set/modified either on `vm define` or via the
`vm meta` command. For the API it is set/modified either on a POST to
the `/vm` endpoint (during VM definition) or on POST to the `/vm/<vm>`
endpoint. For the API this replaces the previous reserved word for VM
creation from scratch as this will no longer be implemented in-daemon
(see #22).

Closes #52

Joshua Boniface 983daceaed Fix shutdown abort during restart 
Restart state, being different from shutdown, would trigger an abort of
the shutdown. Fix this by including restart in the valid states to
continue.

Joshua Boniface 7c4d18691a Implement configurable replcfg (node-side)

Joshua Boniface e92a57606d Use better forceful arping command 
Send ARP responses with the source IP in it to force update even if the
old primary did not cleanly terminate (during fencing for instance).

Joshua Boniface ef3b6b3723 Arping 3 times instead of 2 
During fence 2 is not always enough for the network to recognize the
change in primary coordinator.

Joshua Boniface 3b27a88128 Allow abort of shutdown state 
Adds some logic to allow an active shutdown state to be aborted by
changing the VM to another state. Useful mostly if a VM is doing funky
things and not responding to the shutdown, but the administrator either
doesn't want to wait for the timer to expire (forcing an immediate
termination) or wishes to abort the shutdown attempt.
