Joshua Boniface cd860bae6b Optimize VM list in API 
With many VMs this slows down linearly. Rework it a bit so there are
fewer calls to getInformationFromXML and so the processing could happen
in parallel at some point.

Joshua Boniface 60e1da09dd Don't try any shenannegans when updating NICs 
Trying to do this on the VMInstance side had problems because we can't
differentiate the 3 types of migration there. So, just update this in
the API side and hope everything goes well.

This introduces an edge bug: if a VM is using a macvtap SR-IOV device,
and then tries to migrate, and the migrate is aborted, the NIC lists
will be inconsistent.

When I revamp the VMInstance in the future, I should be able to correct
this, but for now we'll have to live with that edgecase.

Actually removes these entire sections of dead code; the daemon-common
library does no formatting at all since it is no longer used by the CLI.

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.

locks as well since these are more consistent.

Joshua Boniface 84ade53fae Add locks for VM state changes 
Use exclusive locks during API events which change VM state. This is
fairly critical to avoid potential duplicate updates. Only implemented
for these specifically required functions to avoid major performance
hits elsewhere.

Joshua Boniface ce60836c34 Allow enforcement of live migration 
Provides a CLI and API argument to force live migration, which triggers
a new VM state "migrate-live". The node daemon VMInstance during migrate
will read this flag from the state and, if enforced, will not trigger a
shutdown migration.

Joshua Boniface 07577a52a9 Implement wait support for various VM commands 
Implements wait support for VM restart, shutdown, move, migrate, and
unmigrate commands, similar to node flush/node unflush.

Includes some additional refactoring of the move command to make its
operation identical to migrate, only without recording the previous
node.
