* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: osa: Disable haproxy ssl configuration"
  - xci: osa: Disable haproxy ssl configuration

    The self-signed certificates are causing troubles so until we implement
    a proper certificate chain in XCI we should disable the SSL endpoints.
