CLOUDSTACK-2914: lbScheme Public should be specified in NetworkOffering

NetworkOfferings now require a mandatory scheme in the
serviceCapabilityList to create a VPC loadbalancer on the public side.
This commit fixes the test for VPC networks. Additionally there needs to
be a fix for making this the default behaviour so as not to hurt the
backwards compatibility.

test still fails because of CLOUDSTACK-2915 however which is a related
network ACL backwards compat issue. See bug for more details.
