Modernize repo language

[rfultz]

Summary

What we're after:
We've had discussions about it and there's a growing movement to remove racist terminology from our code (i.e. master, slave, blacklist, whitelist, black list, white list)

Before starting work, are there other terms we should replace?

Completion criteria

Our code and documentation will be updated to remove racist terms like "master", "slave", "whitelist", and "blacklist".

Tech steps or considerations

Code and documentation should be updated, all functionality maintained.
