Hello!
I wanted to make pulp-cli portable and build PEX archive out of it but the
latest pex (2.1.56) fails to do so:
```
$ pex -v -c pulp 'pulp-cli[pygments]'
...

```
As I understand, this happens because setup.py does not
<https://github.com/pulp/pulp-cli/blob/cfa096774946c0d0100d5263fa65f5b251a8c566/setup.py#L47>
explicitly declare a dependency on setuptools (which contains pkg_resources
unlike the packaging lib). If that's correct, could you add the dependency
please? If not, do you know what can be the issue here?
Also, it seems to me pkg_resources is only used to load CLI plugins here
<https://github.com/pulp/pulp-cli/blob/cfa096774946c0d0100d5263fa65f5b251a8c566/pulpcore/cli/common/__init__.py#L163>.
However, the document which this code mentions does not include any
mentions of pkg_resources. Can it be that a better fix here is to update
the plugin loading function?
Thanks!
