Issue DM-1249: Reimplement CSS using JSON-packing, czar kazoo + c++ snapshotting phase 1
Transient cache for CSS, populated from python, no C++ interface to zookeeper. Pack multiple keys using json. Tenative packing spec is in DM-705 The v1 implementation transitions the zk access from the c++ layer into python, with code that understands how to unpack json-encoded data. This can coexist with the existing qserv_admin zk schema. v2 applies packing/unpacking logic in the creation/manipulation code in qserv_admin.
