Revert "verify_ssl: true for osbs store metadata plugin"

This reverts commit dd3b55935f.

This change is going to require a bit more work because the cert in
question is self-signed and auto-generated by the openshift-ansible
cluster bootstrapping since it's only internal to the cluster.
Patrick has an idea for how to handle this going forward, will
follow up later.
