Description of problem:
From time to time the installation fails with something like the one below:

2022-01-03 16:33:27.936 | level=debug msg=Generating Terraform Variables...
2022-01-03 16:33:27.940 | level=info msg=Obtaining RHCOS image file from 'https://rhcos-redirector.apps.art.xq1c.p1.openshiftapps.com/art/storage/releases/rhcos-4.8/48.84.202109241901-0/x86_64/rhcos-48.84.202109241901-0-openstack.x86_64.qcow2.gz?sha256=e0a1d8a99c5869150a56b8de475ea7952ca2fa3aacad7ca48533d1176df503ab'

Version:
4.8.0-0.nightly-2021-12-23-010813 but we see it for other versions as well
IPI

I expect the installer to have some sort of retry mechanism.
