changed instanceSidecarConfiguration not applied

due to a memory problem I wanted to set the BarmanObjectstore `.spec.instanceSidecarConfiguration.logLevel: trace`
after applying the logLevel, it was set at the ObjectStore

but the sidecar did not change

after restarting the container, the logLevel was correctly set to trace

Start by tracing how changes to BarmanObjectStore.spec.instanceSidecarConfiguration are reconciled into the running sidecar. Reproduce the logLevel change from the issue and compare the ObjectStore setting with the sidecar configuration before and after a container restart. Done means the sidecar applies the new log level without requiring a restart.
