libvirt also allows extra parameters for some of these transport types, but this just
providers the basic support.
Updates from set 1 to set 2:
-See patch Extend the VirtualSystemMigrationSettingData to include an attribute for

Reorganize VSMigrationService to prepare for URI support.
Since both MigrateVirtualSystemToHost() and MigrateVirtualSystemToSystem() both need to
get the values from MSD in the same way, might as well put the MSD calls in migrate_do
(since both call this function).

Extend the VirtualSystemMigrationSettingData to include an attribute for transport
method.
Possible transport methods are those supported by libvirt: ssh, tls, unix sockets, and
tcp.
Updates from set 1 to set 2:
-Remove verbose description.

Add URI support to VSMigrationService.
For the vs_migratable() call, the destination uri is hardcoded to SSH. This will call
will be updated in a later patch so that it pulls the proper transport value from teh
MSD.
Update from set 1 to set 2:
-Consolidate dest_uri() and transport_from_class()
-Fix missing dereference for the uri variable in get_migration_uri().
