Issues with Running Examples

## Describe the bug
There are several issues with trying to run the examples from scratch (on an M1 Mac). I would submit a PR to solve these but I probably don't have time at the moment.

## To Reproduce
Try to follow the existing README on an M1 Mac.

## Issues and Solutions
### RabbitMQ won't run correctly using Conda

#### Solution

Add comment to README mentioning you can also run this command to run RabbitMQ
`docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.11-management`

### It is unexpected for the user to get a password required when running the example and there is no explanation of how to proceed
#### Solution
Initially add a comment to README describing that the username and password are printed on the command line.
Long term, likely don't use public by default for the examples OR provide a way to disable that using a command line argument or environment variable.

### The instruct_hf_pipeline.py doesn't work out of the box because the dependencies are not in the requirements.txt file
#### Solution
Either add the dependencies to requirements.txt or add it in the README or print a more helpful message when running that example.

Start with the existing README and requirements.txt, then try the examples on an M1 Mac as described. Check the RabbitMQ setup, the password guidance, and instruct_hf_pipeline.py's dependencies. Done means the documented examples run from scratch or clearly explain the required commands, credentials, and dependencies.
