---------------

The build-docker-images failure for stx-keystone-api-proxy is because it could not find zerorpc.

ERROR: Could not find a version that satisfies the requirement zerorpc (from sysinv===1.0->-c /tmp/wheels/upper-constraints.txt (line 728)) (from versions: none)
ERROR: No matching distribution found for zerorpc (from sysinv===1.0->-c /tmp/wheels/upper-constraints.txt (line 728))
The command '/bin/sh -c /opt/loci/stx-scripts/install.sh' returned a non-zero code: 1
Command (docker) failed, attempt 5 of 5.

Failed to build stx-keystone-api-proxy... Aborting

So we need to add that to the wheel
