Advertise which network backend is in use in DB

For clients to determine which network backend is in use a key "network_backend" is added to the Host.software_version map on each host. The value of this key can be (same as the contents of /var/xensource/network.conf):

    * bridge: the Linux bridging backend is in use;
    * openvswitch: the Open vSwitch backend is in use.
