This API extends catalog tool to search node and partitions using unrestricted search and accertACI.

    The mains goal here are:
       - raise Unauthorized (instead NotFound) when the object exists but you cannot have access
       - Globaly cache when you find a computer since this is quite intense operation
       - Be able to search regardless security (which is required for some usecases).

   The internal API only store dict, rather them store xml.

   slapos.slap.slap is only used on SlapTool context, releasing the
internal API on having it.

   The approach is deprecate the usage of it as soon clients relies on
  a different API.

  Those files tend to be modified quite often, including on the sub projects.

 The site and translation data is updated after the installation,
 causing the delta. For now we ignore it and we update translation
 later.

   The purpose of the restricted parameters were to keep hidden values which weren't part of the schema on the parameter form, for a simplified version of the form.

   Since the user can always edit the raw values (over XML) this feature is undesirable, since if produce inconsistent outcome.

   It is the duty of software release to produce a simplified version, with a restricted list of acceptable parameters.

  Drop non required new line (it will be added anyway).

  The "bad" sample are examples that are miss used, but it should still works (as expected by the format).

  The first example are from the implementation of boolean using enum + strings.

   Boolean should be handled as boolean not as strings.
   Selection should include default value even if they are outside the enum list.

   Keep the xml_output as it is even if the form is Invalid, this allow the user force post (since it is the user decision).

   If the textarea is blank/empty, add the default xml (empty values) in place, otherwise the user cannot re-render the parameter form back.

slapos.libnetworkcache now needs the signature key to have a
corresponding certificate in signature-certificate-list so we need to
give signature_certificate_list to NetworkCacheClient constructor.

  Include more sample data.

   This makes eventual reuses for testing and demostration easy.
