* NotFound Errors are now handled by API

Can replace the following SlapTool calls:
* softwareReleaseError
* availableSoftwareRelease
* buildingSoftwareRelease
* destroyedSoftwareRelease

    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.
