Use a pair of transitional states, "takeover" and "relinquish", when
transitioning between primary and secondary coordinator states. This
provides a clsuter-wide record that the nodes are still working during
their synchronous transition states, and should allow clients to
determine when the node(s) have fully switched over. Also add an
additional 2 seconds of wait at the end of the transition jobs to ensure
everything has had a chance to start before proceeding.

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.

Finishes a basic form of OVA provisioning within the existing create_vm
function. Future plans should include separating out the functions and
cleaning them up a bit more, but this is sufficient for basic operation.
Closes#71
Add functions for uploading, listing, and removing OVA images to the API
and CLI interfaces. Includes improved parsing of the OVF and creation of
a system_template and profile for each OVA.
Also modifies some behaviour around profiles, making most components
option at creation to support both profile types (and incomplete
profiles generally).
Implementation part 2/3 - remaining: OVA VM creation

Add management of the pvcprov database with SQLAlchemy, to allow
seamless management of the database. Add automatic tasks to the postinst
of the API to execute these migrations.
Allow the user to specify other, non-raw files and upload them,
performing a conversion with qemu-img convert and a temporary block
device as a shim (since qemu-img can't use FIFOs).
Also ensures that the target volume exists before proceeding.
