Warm migrations from oVirt/RHV providers fail when "Skip certificate validation" is enabled.

Warm migrations use CDI's ImageIO importer directly to transfer disk data from oVirt to OpenShift. The CDI importer:
Always validates TLS certificates when connecting to the oVirt ImageIO service
Required either:
   - A valid CA certificate in a ConfigMap, OR
   - An insecureSkipVerify flag in the DataVolume spec (which didn't exist)
Without either, it failed with: "x509: certificate signed by unknown authority"

1. Create ocp remote provider (skip SSL)
2. create RHV provider (skip SSL)
3. select mtv-rhel8-warm-sanity-nfs' VM and start warm migration 

'Unable to connect to imageio data source: Error creating connection: tls_error:
          TLS error, check your CA certificate settings (failed to validate the connection
          (Post "https://rhev10-m.gsslab.rdu2.redhat.com/ovirt-engine/sso/oauth/token":
          tls: failed to verify certificate: x509: certificate signed by unknown authority))'

warm migration with TLS insecure (skip cert validation) should work
