Update quickstart to point to v1beta3 manifests

[Tom Cammann]

The quickstart guide doesn't specify you have to use the v1beta3 manifests, if the old manifests are used magnum will produce a stack trace after it cannot find the name in the manifest.

In the quickstart guide:

      cd ~/kubernetes/examples/redis
      magnum pod-create --manifest ./redis-master.yaml --bay testbay

Should be:

      cd ~/kubernetes/examples/redis/v1beta3
      magnum pod-create --manifest ./redis-master.yaml --bay testbay
