Updates and fixes to NIC config template routes

This change adds the ManagementInterfaceDefaultRoute parameter
for setting the Management network as the default route in some
deployments. Notes were added to indicate that if the Management
network is used as the default gateway, then the default route
on the control plane should be commented out.

The sample network-environment.yaml was modified to include the
ManagementInterfaceDefaultRoute, but this is commented out like
the rest of the Management network parameters.

This change also adds the ControlPlaneDefaultRoute and
ExternalInterfaceDefaultRoute to all templates, so that if the
networks are customized, the NIC configs can be modified without
having to modify the parameters section of the template. The
default for the ExternalInterfaceDefaultRoute is '10.0.0.1', and
the default for ManagementInterfaceDefaultRoute is set to 'unset'.

This change also converts the single-nic-linux-bridge-vlans from
DHCP to static IPs on the Control Plane Interface, bringing these
templates in line with the rest of the NIC config templates. The
parameters needed to be updated in these templates as well.

The controller-v6.yaml templates had a default value of "10.0.0.1"
for the ExternalInterfaceDefaultRoute. This was confusing, and is
now undefined.

This change also sets a default gateway on the Control Plane in
controller-no-external.yaml templates.
