Here's some notes for anyone who wants to build mcrouter on Ubuntu 22.04

1. Replace mcrouter/m4/ax_python_devel.m4 by the latest version from https://github.com/autoconf-archive/autoconf-archive/blob/master/m4/ax_python_devel.m4
2. Update gtest version number in mcrouter/scripts/recipes/gtest.sh.
3. Remove -j3 from mcrouter/scripts/get_and_build_by_make.sh
4. Change apt packages

See my fork for detail: https://github.com/facebook/mcrouter/commit/93db39ff5f3c77dc47129ea7f1fd9095ab549a37

I'm not sure whether it causes other problem after upgrading some dependencies.
