Add ability to import schema defined in JSON format via file path or directly via JSON string. This implementation doesn't migrate or update already defined schema elements. Neither it removes existing defined elements. SchemaInitStrategy is defined in mind to be able to implement migration and more advance schema management, even so current JSON schema importer implementation is fairly simple. This work is made in hopes to simplify schema definition for beginners, speed-up prototypes development based on JanusGraph, and simplify testing. Signed-off-by: Oleksandr Porunov <[email protected]>
