Use oslo.utils and oslo.serialization

Left timeutils and strutils in openstack/common since they are used in
openstack/common/apiclient and memorycache.

-JSON related utilities.

-This module provides a few things:
-
-    1) A handy function for getting an object down to something that can be
-    JSON serialized.  See to_primitive().
-
-    2) Wrappers around loads() and dumps().  The dumps() wrapper will
-    automatically use to_primitive() for you if needed.
-
-    3) This sets up anyjson to use the loads() and dumps() wrappers if anyjson
-    is available.
