So taking a blind guess without actually looking at anything besides this email
my thinking is that you aren't installing neutronclient in /usr/bin in that job.
Either it's being installed in the tox venv only or going into /usr/local/bin or
something like that. There is a parameter to give tempest-lib the bin dir where
the cli commands live. You need to make sure that's set to where ever you're
installing the CLI commands.
