ocp-test: patch console object to include managementState

Closes issue: nerc-project/operations#912
The console object "cluster" was giving error due to a missing managementState. Since we have a cutom console config we need to add a patch which
includes this line with the value Managed, so the managementState does not fall off the console resource in the future.
