tap-test-data

Many taps have statically defined schemas so you can --discover without credentials to get the catalog schema for all streams available. Given that catalog as input it would be nice to have a tap that generates fake data that conforms to it. This would be very helpful for testing pipelines without credentials. https://github.com/lk-geimfari/mimesis or https://github.com/joke2k/faker can be used to generate fake data.

This is somewhat similar to https://github.com/meltano/sdk/issues/1009 but that requires the tap to pull real data in order to mask it.

@edgarrmondragon any thoughts? I want to test out https://hub.meltano.com/extractors/tap-amazon-sp but I dont have credentials which made me wonder if we could generate data as if I do. This would unlock anything downstream and would expect that the tap conforms to its own schema, otherwise thats a bug anyways.
