Hi I try to adress #1026 for snowflake, turn Multiple primaryKey (a.k.a composite key) as Unique constraint for snowflake

[Auguronomics]

The fact some existing data contracts in dcs ( datacontract specification format) when instanciate with :

        "sql", server="staging"
    )````
the automatic translation from dcs to odcs prefill the physicalType in Schema Properties, and overload the existing 
`sql_type_converter` function `def convert_to_sql_type(field: Union[SchemaProperty, FieldLike], server_type: str) -> str:
    physical_type = _get_config_value(field, "physicalType")`

Should I refactor the Test or Implement a better logic here : def _convert_models_to_schema(models: Dict[str, Model], definitions: Dict[str, Field] = None) -> List[SchemaObject]:
"""Convert DCS models dict to ODCS schema list."""
schema = []
for model_name, model in models.items():
schema_obj = SchemaObject(
name=model_name,
physicalType=model.type,
description=model.description,
)
