Joshua Boniface f75216d946 Make force_migrate not replace existing node 
Previous to this, if once force-migrated a VM, the previous_node value
would be updated to the current node, which is likely never what an
administrator would want. Change this functionality so that the previous
node value is not changed, and update the documentation to reflect this.

Joshua Boniface 5ac3d55b8d Always use the passed domain in messages 
Don't ever output an ugly UUID unless that's what was actually sent to
the function. Makes output much much nicer, especially on errors.

Joshua Boniface 6e2dfc1704 Reorganize file before refactoring 
This is the largest of the function files, and unlike the others is
cleanly split into four types. Reorganize the file and function
definitions around those types to make it easier to navigate, and do so
separately before refactoring for API.

Joshua Boniface 77e215b0eb Don't queue flushes without --wait 
Don't try to queue up a flush when there is already a flush lock; direct
the user to use --wait (which will actually wait before triggering the
new action), or try again later.

Prevents returning immediately to give the cluster some breathing

as well to prevent other clients from attempting this as well.

show the number of allocated vCPUs. To preserve space, no longer
show the host CPU count in the list.

Joshua Boniface c19902d952 Implement flush locking for nodes 
Implements a locking mechanism to prevent clobbering of node
flushes. When a flush begins, a global cluster lock is placed
which is freed once the flush completes. While the lock is in place,
other flush events queue waiting for the lock to free before
proceeding.

Modifies the CLI output flow when the `--wait` option is specified.
First, if a lock exists when running the command, the message is
tweaked to indicate this, and the client will wait first for the
lock to free, and then for the flush as normal. Second, the wait
depends on the active lock rather than the domain_status for
consistency purposes.

Closes #32

Joshua Boniface b6ecd36588 Implement domain log watching 
Implements the ability for a client to watch almost-live domain
console logs from the hypervisors. It does this using a deque-based
"tail -f" mechanism (with a configurable buffer per-VM) that watches
the domain console logfile in the (configurable) directory every
half-second. It then stores the current buffer in Zookeeper when
changed, where a client can then request it, either as a static piece
of text in the `less` pager, or via a similar "tail -f" functionality
implemented using fixed line splitting and comparison to provide a
generally-seamless output.

Enabling this feature requires each guest VM to implement a Libvirt
serial log and write its (text) console to it, for example using the
default logging directory:

```
<serial type='pty'>
    <log file='/var/log/libvirt/vmname.log' append='off'/>
<serial>
```

The append mode can be either on or off; on grows files unbounded,
off causes the log (and hence the PVC log data) to be truncated on
initial VM startup from offline. The administrator must choose how
they best want to handle this until Libvirt implements their own
clog-type logging format.
