Add connector for any HTTP endpoint

[matthew-wong-bcg]

Is your feature request related to a problem? Please describe.

The only connectors that exist currently are for existing models with clearly defined APIs. There is no way for a user to specify any HTTP endpoint to get a response.

Describe the solution you'd like

I want to be able to use ARTKIT with any endpoint that accepts a payload.

Describe alternatives you've considered

None

Additional context

It seems like a version of the existing HuggingFace connector could be leveraged
