Teach build-local-images to build service-catalog
Building images from RPM takes quite a bit of time, so add service
catalog to the local image build list. A prerequisite for this task is
to have the service catalog binaries compiled, which is done with #1:
1)
cmd/service-catalog/go/src/github.com/kubernetes-incubator/service-catalog/hack/build-go.sh 
2) hack/build-local-images service-catalog
The first script uses the origin tooling to build in the same way as the
RPMs are built. Note that a new "enable_default" key has been added to
the image_config and set to False for service catalog so that it is not
built unless directly specified (as indicated in #2).
