Health check does not work when gitlab_rails[allowed_hosts] set

Summary

When next options provided, the gitlab-healthcheck-rc should not query localhost, but query allowed_hosts

Steps to reproduce

    external_url "http://office.black-list.info/gitlab"
    gitlab_rails['allowed_hosts'] = ['office.black-list.info']

What is the current bug behavior?

    # cat /opt/gitlab/etc/gitlab-healthcheck-rc
    url='http://localhost:80/gitlab/help'
    flags='--insecure'

What is the expected correct behavior?

    # cat /opt/gitlab/etc/gitlab-healthcheck-rc
    url='http://office.black-list.info:80/gitlab/help'
    flags='--insecure'
