Drop support for cpu_affinity (#5525)
This has no useful purpose on python3, and is generally a source of confusion.

-# CPU affinity mask. Setting this restricts the CPUs on which the
-# process will be scheduled. It is represented as a bitmask, with the
-# lowest order bit corresponding to the first logical CPU and the
-# highest order bit corresponding to the last logical CPU. Not all CPUs
-# may exist on a given system but a mask may specify more CPUs than are
-# present.
-#
-# For example:
-#    0x00000001  is processor #0,
-#    0x00000003  is processors #0 and #1,
-#    0xFFFFFFFF  is all processors (#0 through #31).
-#
-# Pinning a Python process to a single CPU is desirable, because Python
-# is inherently single-threaded due to the GIL, and can suffer a
-# 30-40% slowdown due to cache blow-out and thread context switching
-# if the scheduler happens to schedule the underlying threads across
-# different cores. See
-# https://www.mirantis.com/blog/improve-performance-python-programs-restricting-single-cpu/.
-#
-# This setting requires the affinity package to be installed!
