   Also add test for verify if user can close ticket by himself

   Change to use the proper API from ticket_slap_interface_workflow.

   Since the ticket could be seen by multiple users, don't force sender be the Ticket owner.

  Now the activities takes longer to run and configure the site

    It makes no sense now evaluate this using Grade System, but provide reports with helpful information  rather them evaluation.

  Re-serialise the object from the dict after hit cache is slow enough
to cause problems ounder high load.

  This change preserve the previous behaviour reaching the final XML
from cache keeping performace on SlapTool and allowing new
implementation benefit from cache at same time.

  Fixup test to match xml with xml.

    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.

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