* This inverts the --live logic on migrations in Server->migrate_virsh() to default to live.

* Adds a "sensitive" DB connection to ocf:alteeve:server when migrating a VM. This is needed so that migrations can be done cold or live, based on servers -> server_live_migration.
This resolves issue #284.
