noha: Re-enable Horizon dashboard, fix CSS

- ha, noha: Fix misaligned python 3 requirement for Horizon:
  * python3-pylibmc
- ha, noha: Partially revert commit 63b712d:
  "[Horizon] Drop the obsolete Horizon workaround"
  Since we switched back from MCP Horizon package to UCA,
  fix misaligned expected static resources location.
- noha: Enable nginx proxy on ctl01 node for serving the Horizon
  dashboard at http://<cluster public VIP>:80 (http only, no SSL).
