Transformation schema for nodes and edges with view centric and model centric

[nimeshawij]

Description

Transformation schema for nodes, edges in both view centric and model centric

_api\transformations\schema.py

1. Added condition to check destination.type "nodes" or "edges" or "instances", then set the resource path /transformation/schema/instances.

Because all other resource paths are in the format /transformation/schema/{destination.type}

2. withInstanceSpace, isConnectionDefinition, instanceType are optional

3. Examples

• Get the schema for a transformation producing nodes::
• Get the schema for a transformation producing edges::
• Get the schema for a transformation producing instance type data model::
• Get the schema for a transformation producing instance relationship data model::

tests\tests_integration\test_api\test_transformations\test_schema.py

Added test_nodes_with_view(self, cognite_client) test_edges_with_view(self, cognite_client) test_instance_type_data_model(self, cognite_client) test_instance_relationship_data_model(self, cognite_client)
