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.

Joshua Boniface d28b1ba133 Support removing VMs (and disks) from PVC clients 
Adds full support for removing a VM entirely, including its RBD disks,
via the PVC client(s). Avoids needing an undefine + manual removal.

Joshua Boniface 08cb16bfbc Revamp VM migration handling 
This was very old code that was hard to follow and quite fragile, with
failures and infinite loops occurring fairly frequently. These changes
make the code more robust, including the addition of timeouts, some code
cleanup, and some improvements to the logical flow.

Also forces the libvirt migration to occur on the cluster network, which
couples to changes in the libvirtd listen (via pvc-ansible) and in
Daemon.py via the previous commit.

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 85a5a8a0c9 Disable tx offloading on bridge interfaces 
Reference: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717215#68

Without this, DHCP fails when traversing only the local bridge, for
Debian Jessie or earlier (and possibly other OSes as well), due to the
missing UDP checksums. This disables the offload and hence reenables
the checksums even on the software-only bridge.

Also rearranged the steps and added comments arround this section to
better clarify what each command is doing.

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 9a0554fdbe Remove all volumes from pool on removal 
Technically not needed, but otherwise random errors may be thrown,
so best to be explicit.

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.
