Joshua Boniface b851a6209c Catch all other exceptions in subprocess run 
Found a rare glitch where the subprocess pipes would not engage, causing
a daemon crash. Catch these exceptions with a retcode of 255 instead of
bailing out.

Closes #124

Joshua Boniface 5ceb57e540 Handle emptying corrupted console log files 
Libvirt will someones write junk out to console log files, which breaks
the log parser deque with a UnicodeDecodeError.

If this happens, clear the log and re-open the deque again for newer
updates.

Add nicer easy-to-find (yay ASCII art) banners for the startup printouts

to prevent hassle messages and a version string in the API daemon file.

Joshua Boniface ac3ef3d792 Revamp fencing order 
Prevents unnecessarily excessive timeouts if IPMI connections time out;
before, would have to go through 3 timed out commands at ~20s each
before failure was registered; reduced to 1 if the first times out.

Joshua Boniface 3705daff43 Better handle failing RBD lock frees 
If the VM is not in a stop state, failing to free the lock is now
considered a fatal error and will put the domain into fail state,
aborting the start. This is better than being unsafe or trying to start
a VM which will fail to boot due to read-only volumes.

Joshua Boniface 7c99a7bda7 Safely reset RBD locks on failed VMs 
Should correct issues on cold start as well as if a VM crashes
uncleanly, which would prevent the VM from starting due to stale RBD
locks.

This implementation has four parts:
  1. Update how IP addresses are handled, specifically by replacing all
  previous instances of "vni_ipaddr" with "vni_floatingipaddr", and then
  adding the "vni_ipaddr" with the real data for this node's IPs. Also
  include the storage IPs in this where they weren't before, so each
  this_node actually has the local IPs plus floating IPs. This enables
  the next two steps.
  2. Modify flush_locks to take this_node as an argument, and update the
  run_command function to only operate against this node, rather than on
  the primary coordinator.
  3. Have the flush_locks check each lock against the current node, to
  verify that the lock is actually held by the current node. This is the
  only way to do this safely. During fencing, we override this by not
  passing a this_node which bypasses this check.
  4. Have the VM start do the check for VM failure/startup and execute a
  flush_locks before actually starting the VM.

Joshua Boniface 89c7e225a0 Move OSD stats uploading to primary only 
Instead of each node uploading its own OSD stats, which would not work
if the PVC daemon wasn't running, instead have the primary upload stats
for all OSDs in the cluster.

Joshua Boniface ec0b8acf90 Support per-VM migration type selectors 
Allow a VM to specify its migration type as a default choice. The valid
options are "default" (i.e. behave as now), "live" which forces a live
migration only, and "shutdown" which forces a shutdown migration only.
The new option is treated as a VM meta option and is set to default if
not found.
