Command line flags are not respected

[bacherfl]

The command line flags which are passed to the lifecycle operator are currently not adopted correctly if they are set to anything else than the default. E.g. when setting the --metrics-bind-address flag to 127.0.0.1:8087, the following logs are produced by the operator:

2023-06-29T18:17:24Z	INFO	controller-runtime.metrics	Metrics server is starting to listen	{"addr": ":8080"}
