Failed to build centos container

While building the container to setup the developer environment for centos7, the container will fail to build because newer versions on git-review do not support python2.7, from the release notes:

https://docs.opendev.org/opendev/git-review/latest/releasenotes.html

"As of this release, git-review no longer supports running under the Python 2.7 interpreter. The major version component has been increased accordingly. Users wishing to use git-review with Python 2.7 can cap their installations like pip install "git-review<2", though pip version 9 and later will use python_requires package metadata to avoid installing git-review on an unsupported interpreter. Future removal of support for Python 3 minor versions will only result in a minor version increase for corresponding git-review releases."

Traceback is below:
