salt-cloud vmware provisioning offline minion bootstrap hangs when internet not reachable.

Description of Issue

When provisioning to target networks that have no internet access, it seems the bootstrap sh still tries to reach external mirrors. Or so it seems. (gleaned from our fw logs). Note that the source OS template is up to date and epel-release is installed and up to date.

Start with the salt-cloud provisioning command and the generated deploy.sh output, focusing on install_centos_stable_deps() and the -R repository path. Reproduce the CentOS 7.6 offline bootstrap with the supplied local repository and debug logging. Done means provisioning completes without attempting unreachable external mirrors or hanging during dependency installation.
