docs: Return the value for the CIM-XML extension header field 'CIMObject', using
      the given object.
  
      This function implements the rules defined in DSP0200 section 6.3.7
      "CIMObject". The format of the CIMObject value is similar but not identical
      to a local WBEM URI (one without namespace type and authority), as defined
      in DSP0207.
  
      One difference is that DSP0207 requires a leading slash for a local WBEM
      URI, e.g. '/root/cimv2:CIM_Class.k=1', while the CIMObject value has no
      leading slash, e.g. 'root/cimv2:CIM_Class.k=1'.
  
      Another difference is that the CIMObject value for instance paths has
      provisions for an instance path without keys, while WBEM URIs do not have
      that. Pywbem does not support that.
