Faster JSON encoder/decoder

Improve performance of FreeIPA's JSON serializer and deserializer.

* Don't indent and sort keys. Both options trigger a slow path in
  Python's json package. Without indention and sorting, encoding
  mostly happens in optimized C code.
* Replace O(n) type checks with O(1) type lookup and eliminate
  the use of isinstance().
* Check each client capability only once for every conversion.
* Use decoder's obj_hook feature to traverse the object tree once and
  to eliminate calls to isinstance().
