Enforce schema on vertex creation

Browse Source 
- Separating schema definition from schema validation
- Updating vertex_accessor and db_accessors with necessary methods
- Adding a primary label to Vertex
- Adding schema tests
- Updating existing tests for storage v3, and deprecating old:
  - interpreter => interpreter_v2
  - query_plan_accumulate_aggregate => storage_v3_query_plan_accumulate_aggregate
  - query_plan_create_set_remove_delete => storage_v3_query_plan_create_set_remove_delete
  - query_plan_bag_semantics => storage_v3_query_plan_bag_semantics
  - query_plan_edge_cases => storage_v3_query_plan_edge_cases
  - query_plan_v2_create_set_remove_delete => storage_v3_query_plan_v2_create_set_remove_delete
  - query_plan_match_filter_return => storage_v3_query_plan_match_filter_return
