Migration to Python3? SafeConfigParser

[justinb-dfw]

Environment

• How did you install GRR? [e.g. from release DEB, HEAD DEB, PIP package, source]
  Docker Compose
• What GRR version are you running?
  Latest
• What operating system does the GRR server run on? [e.g. Ubuntu 18.04]
  Docker on Mac OS 15.4.1
• What operating system does the affected GRR client run on, if applicable? [e.g. Windows 10]
  Mac OS 15.4.1

Describe the issue
It seems like the script is utilizing antiquated python such as SafeConfigParser - can we make sure the 2to3 futures library is included so it doesnt break in later python3 enviornments?

Ran the command:
CFLAGS=-stdlib=libc++ pip install grr-response-client-builder

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

Additional context
Was working on this as the mac osx client doesnt seem to work on Apple Sillicon?
