update cloudooo configuration as well.

The inline recipe for ERP5 has been improved and converted into recipe,
which is reused for NEO.

Templates are instanciated only if they're used, so no need anymore to
wrap them with:

  {% if slap_software_type == software_type -%}
  ...
  {% endif %}

Not perfect yet, as some strings end in configuration files for example
and need escape mechanisms aware of individual configuration file syntaxes.

This work has nothing to do in erp5-component branch, and is preventing it
from being merged to erp5 banch more often.
Conflicts because of non-reverted
6d1a9805 have been resolved to that its
intent is preserved with non-cluster ERP5 SR.

This reverts commit 77976a14.
This reverts commit 7aa1d92c.
This reverts commit 80062015.
This reverts commit 36ed58f2.
This reverts commit 1fe3f466.
This reverts commit 7731726a.
This reverts commit eb2016c4.

Only check if cloudooo and openoffice port is listenning.

All ERP5 profile is now in a single place.
Moreover, use slapos.cfg stack.

Also, hide ip_list for the same reason: it's a partition property, not a
partition parameter. It is not handled yet (not needed).
Also, rework documentation a bit.
