Switch to using ADC for receiving samples, events

[WardLT]

This Issue is our initial step for tracking how we integrate with the Argonne Data Cloud (ADC). Future issues will be created as the ADC and it's SDK emerge.

Issues we'll need to solve:

• [x] Purge mention of FastAPI from the documentation and examples
• [x] Implement "get all samples" utility function
• [x] Be able to use SDK to create a websocket, route events from socket to planner
• [x] Add SDK to the system requirements
• [ ] Provide documentation for how to authenticate with ADC
• [x] Implement tests that mock ADC requirements

Implement "get all samples" utility function

I think the following should be enough, at least for the raw response dict from the API which you can later iterate through:

from adc.client import ADCClient

token = <token you get from adc>
client = ADCClient(token)
studies = client.get_studies()

Thanks! I added that logic (along with some auto-populate token from env variables) to that with 6f8a58e
