[PLT-1207] Added prompt classification for python object support

[Gabefire]

Description

Please include a summary of the changes and the related issue. Please also include relevant motivation and context.

• Gives the ability to import annotations for prompt response projects
• Made custom prompt classification annotation class for better validation (only one is allowed per label)
• Did some testing and classification annotation class will work for a response (only classification). I had a response custom class but I think that is to complicated and reuses a bunch of code
• Since we are deprecating the data type. I only allowed global keys to be passed in as a dict for data. I don't see the point of adding since we are deprecating.
• Switch the default inference data type to GenericDataRowData to deserialize a label. This improves testing

        ],
    ))

@Gabefire all of my comments are nit(s), optional except the testing one.
I think we need to add an integration test that shows we can upload annotations of this type
