Use Pod IP address for the public interface

[jmesnil]

Use hostname -i to determine the IP address of the Pod and bind the WildFly public interface to it.

Do not bind jgroups.bind_address to 0.0.0.0 (that is incorrect for JGroups). Instead, if JGroups subsystem is defined, the standalone configuration can attach its socket-binding to the public interface so that the Pod IP addres is properly used to identiy JGroups nodes.

Hi @jmesnil. Thanks for your PR.

I'm waiting for a openshift-s2i or openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available [here](https://git.k8s.io/community/contributors/guide/pull-requests.md). If you have questions or suggestions related to my behavior, please file an issue against the [kubernetes/test-infra](https://github.com/kubernetes/test-infra/issues/new?title=Prow%20issue:) repository.

@bparees thanks. When do you plan to push the openshift/wildfly-160-centos7 Docker image with that fix?

[bparees]

@jmesnil normally it happens automatically on merge. It looks like our push job failed and for some reason I did not see a jenkins email from the job. I'll rekick it.
