* Update kuryr-kubernetes from branch 'master'
  - Merge "Add option to deploy coredns"
  - Add option to deploy coredns
    
    As a step to improve testing capabilities of our gates, this commit
    enhances DevStack with support for deploying coredns in our K8s cluster.
    The idea here is to be able to run any tests that are referring to
    services by <namespace>.<service-name>, in particular upstream K8s
    tests.
    
    The tricky part here is that on gate VM's an instance of unbound DNS is
    running on 127.0.0.1:53. As in DevStack-deployed Kuryr pods doesn't
    support IPv6, we couldn't just take IPv6 addresses of upstream DNS from
    unbound configuration and use them in coredns pods. Instead the coredns
    instance is running on host networking and binds to $HOST_IP:53, which
    is also used as value of kubelet's --cluster-dns option, while
    forwarding any upstream DNS requests to the local unbound instance. This
    isn't perfectly how it would be set up in production environment, but
    should be close enough for our purposes.
    
    This change only affects DevStack, so it's completely safe from release
    point of view. coredns gets enabled only on gates running Kubernetes as
    OpenShift gates run openshift-dns already.
