This appears to be causing problems for devstack because `pip install -e $PACKAGE_PATH` installs commands to /usr/bin and not /usr/local/bin on Ubuntu as it did in the past. `pip install $PACKAGE_PATH` continues to install to /usr/local/bin as expected. Devstack is failing because keystone-manage cannot currently be found at the specific /usr/local/bin/ path.

I'll defer to the QA team on how they want to address this. While we can have devstack install an older setuptools version as well, generally this is not considered to be a good idea because anyone doing pip installs outside of devstack may get the newer behavior. It is actually important for us to try and keep up with setuptools changes as a result.

I'm not sure if they would consider `pip install -e` and `pip install` installing to different paths as a bug, and if they did which behavior is correct. It would probably be a good idea to file a bug upstream if we debug this further.

Updates: 
Issue is when setuptools adopts distutils from the standard library (in 48.0.0) and uses it,  downstream packagers customization to distutils will be lost.
- https://github.com/pypa/setuptools/issues/2232

setuptools 49.1.0 reverted the adoption of distutils from the standard library and its working now.

I have closed the devstack bug 1886237  and proposed the revert of capping of setuptools by blacklisting 48.0.0 and 49.0.0 so
that we test with latest setuptools. For now, devstack will pick the 49.1.0 and pass.

In summary, gate is green and you can recheck on the failed patches.
