Add default to network.mtu in j2 in nic configs

Previously all networks was rendered for all roles, and
thus the default set in network/network.j2#L83 would
propgate to the nic config for any role. Since we now
only include properties for network's in role.networks
when passing parameters puppet/role.role.j2.yaml this
default may not propagate to the nic config and can
cause problems if merge-new-params-nic-config-script.py
was used to add new parameters with a role missmatch.

(i.e Updating the Compute roles NIC config file while
specifying the Controller role in  merge-new-params
tool would add the parameter with no default which
causes Property {{network.name}}Mtu not assigned
error when deploying.
