Adding the whole top-level available IPv6 range to the local table
conflicts with tun/tap usage. Instead, add only the IPv6 subranges
actually allocated to a partition.

This was introduced in 081e745e and I don't see how it could have been
useful.

    It was used on OrderBuilder_generateUnrelatedInvoiceList but the code dont relies on it anymore.

Only one line is used per document.
Using REPLACE is better than DELETE / INSERT.

No need for a multi column primary key, as only one line is used per object.
This will speed up update of the table.

An error slipped in 92da569e (slapos_jio: Drop Handlebars, 2022-06-08)

    The forms were removed long ago, and those actions werent removed

When forwarding a request to an external master, e.g. frontend request,
the master might first answer with status code 408 to indicate the
requested resource is not ready.

The slap library wraps the answer into a ComputerPartition object, even
when the master sends 408: in that case the object only contains the
parameters of the original request.

Until now, when the external master answered 408, the proxy simply
forwarded the ComputerPartition object returned by the slap library
with code 200, instead of forwarding code 408.

This played against the assumptions of the slap library in the client
on the receiving end, resulting in a crash. This was the case even when
using `requestoptional` recipe in buildout.

Now the proxy detects when the object returned by the slap library is
actually the result of a 408 answer, and aborts with code 408.
