Looks like the issue is in the following code:

# disable any other repos to avoid downloading metadata

yum install --disablerepo=\* --enablerepo=alocalsync -y yum-utils

yum-config-manager --disable \*

yum-config-manager --enable alocalsync

in ost common/deploy-scripts/add_local_repo.sh

Might be happening due to new yum available now from CentoOS 7.3...

Do we really need to disable all repos when installing yum-utils?
