[AVRO-2051] Remove synchronization for JsonProperties.getJsonProp
This change does two basic things:
1) Makes "props" a private field and requires the subclasses to access it
via the additional methods. This allows some changing of the underlying
implementation a bit easier.
2) Change props to an AtomicReference and makes it act like an immutable
map. The addProp method does a full copy of the map, adds the new value, and
then atomicly swaps in the map thus not affecting other threads that would be
using the value that was "current" when they called the get method.
