Storage operator stuck with Upgradable=Unknown

TRT has unfortunately had to revert this breaking change to get CI and/or nightly payloads flowing again. 
The original PR was https://github.com/openshift/cluster-storage-operator/pull/381.
The revert PR: https://github.com/openshift/cluster-storage-operator/pull/384

The following evidence helped us pushing for the revert:
In the nightly payload runs, periodic-ci-openshift-release-master-nightly-4.14-e2e-metal-ipi-sdn-bm has been consistently failing in the last three nightly payloads. But the run in the revert PR passed.

To restore your change, create a new PR that reverts the revert and layers additional separate commit(s) on top that addresses the problem.

Contact information for TRT is available at https://source.redhat.com/groups/public/atomicopenshift/atomicopenshift_wiki/how_to_contact_the_technical_release_team. Please reach out if you need assistance in relanding your change or have feedback about this process.
