fix(olm-deployer): do not assign owner references to cluster wide objects

[razvan]

Description

Do not set up owner references to cluster wide objects when deploying the listener and secret operators.

Owner references cause these resources to be deleted upon operator upgrades which leaves existing PVCs in an unreconcilable state.
