Issue description

I'm not exactly sure what is going on, but trying to install this an Debian Buster environment (that's where this test is failing), it seems like stestr can't find it's commands.

$ docker run -it  debian:buster /bin/bash

# apt-get update && apt-get install python3 python3-venv

# python3 --version
Python 3.7.3

# python3 -m venv /tmp/venv

I guess the difference here is importlib-metadata from 4.12.0 -> 5.0.0 and ``zipp```

I also tried this in a fresh venv making sure to pre-upgrade pip & setuptools in the venv, but that didn't seem to make a difference to the behaviour

This has now led me to

python/importlib_metadata#411
python/importlib_metadata#409

which seems to be more or less the same problem; imports not quite working with Python 3.7 (which Debian Buster has).

It seems like stevedore might be involved in finding the commands? But 3.5.1 has a fix for this

https://opendev.org/openstack/stevedore/commit/143a3e9f0716690be7343d4d083f65d7624b3d2e

however clearly it's not working. Still unclear what the failing component is ...

I think this is ultimately a stevedore issue https://review.opendev.org/c/openstack/stevedore/+/861695

Order old importlib-metadata results by group
5189992 
A Debian Buster-based zuul-jobs test started failing when using stestr
recently [1].  Upon further investigation, this is a Python 3.7
environment which is affected by a recent breaking change to
importlib_metadata.

It seems stevedore worked around this with
Ib9c2b0a14edea91e97d122d2ac93b650029f918e, which was released with
3.5.1 -- but I was still seeing the issue.

Upon further investigation, the "real_groups" dict being returned here
with importlib-metadata 4.12.0 is in buckets by group, e.g.

 {'group.one': [EntryPoint(name='foo', ... , group='group.one'),
                EntryPoint(name='bar', ... , group='group.one')],
  'group.two': [EntryPoint(name='moo', ... , group='group.two'),
                EntryPoint(name='goo', ... , group='group.two')],
 }

This current code seems to return a dict with entry-points by thier
name, e.g.

 {'foo': EntryPoint(name='foo', ... , group='group.one),
  'bar': EntryPoint(name='bar', ... , group='group.one),
  'moo': EntryPoint(name='moo', ... , group='group.two),
  'goo': EntryPoint(name='goo', ... , group='group.two)
 }

This reorgansies the fixup routine to put entry-points in a bucket by
their group.  With this change, stestr is again finding it's command
plugins.
