A recent update to sysinv added a new import:
https://review.opendev.org/#/c/679457/7/sysinv/sysinv/sysinv/sysinv/common/utils.py
This file is imported in cgcs-patch and caused a tox failure
because it could not be found. This commit updates the tox.ini and
.zuul.yaml files to allow for installation of fm-api.
