Gracefully handle lack of CLA for Gerrit user

Hmmmm, this is perhaps expected with our Gerrit setup:

2024-10-21 15:33:29.899501 Running: git config --get gitreview.username
2024-10-21 15:33:29.900999 ... gitreview.username = onap.gh2gerrit
No remote set, testing ssh://onap.gh2gerrit@gerrit.onap.org:29418/portal-ng/bff

ssh://onap.gh2gerrit@gerrit.onap.org:29418/portal-ng/bff did not work. Description: fatal: No Contributor Agreement on file for user ONAP github2gerrit <releng+onap.gh2gerrit@linuxfoundation.org> (id=8473)https://gerrit.onap.org/r/settings#Agreements

               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
EOFError: EOF when reading a line

However, it doesn't look like we're handling the error gracefully.
We should probably put a fix in place.
