Allow graph schema to include the json fields. This is useful for QA
chain to handle queries that refers to json properties.
For example, for node:
Company(details = Json('market_cap', ...))
graph schema will include 'market_cap' as a json_fields of `details` in
the schema representation, so that when a user ask for
`get market capitalization of company`, QA chain can understand which
subfield to refer to.
Note:
- json property schema is done via by inspecting the first non-null property.
- other changes: refactor the tests, improve the logging

This is to support dynamic schema introduced in https://cloud.google.com/spanner/docs/graph/manage-schemaless-data ``` DYNAMIC LABEL (<label_expr>) DYNAMIC PROPERTIES (<property_expr>) ``` allows we add labels / properties that are dynamically stored as values (as opposed to schema objects). This is useful to manage graph with schema that dynamically evolves (without making schema changes).
