      Description of problem:

      METAL-256 introduced Ironic API proxy pods. The pods start with IPv4, but crash loop if IPv6 is used. Blocks Assisted ZTP flow (This was with converged flow DISABLED)
      [root@ocp-edge34 opt]# oc get pods -n openshift-machine-api

      Apache is used for the underlying proxy, and I believe the ipv6 address probably just needs to be surrounded in brackets to pass syntax.

      + python3 -c 'import os; import sys; import jinja2; sys.stdout.write(jinja2.Template(sys.stdin.read()).render(env=os.environ))'
      + exec /usr/sbin/httpd -DFOREGROUND
      AH00526: Syntax error on line 8 of /etc/httpd/conf.d/ironic-proxy.conf:
      ProxyPass Unable to parse URL: https://fd2e:6f44:5dd8::79:6388/
      Version-Release number of selected component (if applicable):
      OCP hub 4.12.0-ec.3


      How reproducible:


      Steps to Reproduce:

      1. Deploy ocp bm compact/HA cluster with ipv6
      2. Deploy MCE + Assisted Service
      3. Try to deploy a spoke via full ZTP

      Actual results:
      Spoke BMH on Hub cluster do nothing:
      mstat-0                 mstat-master-0-0-bmh                                                  true             10h
      mstat-0                 mstat-master-0-1-bmh                                                  true             10h
      mstat-0                 mstat-master-0-2-bmh                                                  true             10h
      mstat-0                 mstat-worker-0-0-bmh                                                  true             10h
      mstat-0                 mstat-worker-0-1-bmh                                                  true             10h


      Expected results:
      ZTP flow happens and spoke cluster deployed
