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

Similar to recent client changes, don't replace the previous node record

Adds a config flag that turns on the API client following the Primary

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.

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.

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.

none of the volume/snapshot stuff is dynamic; will see as this
