Review need to pin zipp to < 2.0.0

[Alex Kavanagh]

python-zipp (a 2nd level dependency) recently updated to 2.0.x which introduced setuptools requrirement of > 42. However, the rest of the build is at setuptools 41. python-zipp has been pinned in the wheelhouse.txt to < 2.0.0 so that the charm will install. This should be reviewed during the next development cycle.

    Add bug note to wheelhouse.txt to track pinning of python-zipp

    This patch adds a bug note to track the unpinning of zipp.

    (Note the bug is related, as closing the bug will be when zipp can
    be unpinned.)

I don't know if this is related but deploying a newly built octavia charm is resulting in:
