mgr/cephadm: fix test failure on newer python

Tests that touch this enum fail for me locally but pass in the CI. This
seems to be due to new enum related behavior in Python 3.11.
See: https://blog.pecar.me/python-enum
Instead of fixing it as suggested in the above blog, adding a __str__
method works on all python versions I care to know about.
