DeprecationWarning: pkg_resources is deprecated as an API

[hello-binit]

Hello, just wanted to flag this warning I've begun seeing:

/usr/bin/vcs:6: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
  from pkg_resources import load_entry_point

I believe it comes from:

https://github.com/dirk-thomas/vcstool/blob/daf389377310f7f31b2171f51a79af82c31bf3e2/vcstool/commands/help.py#L4

Happy to look into a fix if it's something that would be merged.
