pylint unused-import errors in generated operations

[swathipil]

Hi, I'm seeing the following pylint errors in this generated code:

************* Module azure.schemaregistry._types
azure/schemaregistry/_types.py:2: [I0021(useless-suppression), ] Useless suppression of 'too-many-lines'
************* Module azure.schemaregistry._operations._operations
azure/schemaregistry/_operations/_operations.py:8: [W0611(unused-import), ] Unused import json
azure/schemaregistry/_operations/_operations.py:29: [W0611(unused-import), ] Unused SdkJSONEncoder imported from _model_base
************* Module azure.schemaregistry.aio._operations._operations
azure/schemaregistry/aio/_operations/_operations.py:8: [W0611(unused-import), ] Unused import json
azure/schemaregistry/aio/_operations/_operations.py:30: [W0611(unused-import), ] Unused SdkJSONEncoder imported from _model_base

I believe this is happening because the generated code doesn't use json.dumps() but these are still imported.
