These tasks are needed/useful for a first public release of the operator to make it useful and actually do something.
Further steps would be to roll it out across more operators I guess @nightkr

TODO: This needs further refinement to check whether we really need all of this and whether they need to be done in any specific order

Must have

• Investigate how we can accomodate external ip propagation in the listener operator listener-operator#20
• Define default ListenerClasses listener-operator#2
• ClusterIP ListenerClass mode listener-operator#3

• Remove privileged mode requirement listener-operator#70
• Docs need to mention required permissions listener-operator#72
• Use addresses provided by Listeners for provisioning Secrets listener-operator#95
• Discourage users from adding Listener labels to Pods manually listener-operator#96
• Pod gets stuck initializing if listener name is too long listener-operator#110
