(#16791) Revert "Merge branch 'perf/2.7.x/backport-activesupport-hook-disabling' of https://github.com/daniel-pittman/puppet into 2.7.x"

This reverts commit 3d747177c3e3f690effe620d2f38c7a7d0f7d2d9, reversing
changes made to e45961f2a4160875ed1069b18734d3a6456af831.

This change to how puppet interacts with ActiveRecord causes problems
for systems that load puppet inside Ruby on Rails. Foreman encountered
this. Rather than introduce this change that can break existing installs
of puppet, this performance is not going to be part of 2.7.
