engine: Allow engine to configure management network

The patch eliminates the need of ovirt-host-deploy to
create the management network on top of the installed
host.

The management network will be created once the host
is being activated by the logical network definition
in the data-center.

However, since the network creation relies on the
setupNetworks, no further action will be taken for
non-supported cluster versions.
