Description

At the moment the way information is logged throughout the operator is very inconsistent. Some parts log the name of the deployment, some the name + namespace, some neither of these.

We should try to clean this up and unify it across the operator.

I see basically 2 possible ways:
 1. Add a log formatter utility to always attach name + namespace information to each logged line
 2. Remove namespace + name from everywhere and extract this as part of the logger setting from MDC information the operator sdk already provides (https://javaoperatorsdk.io/docs/features)

We should discuss this on the mailing list as part of this work
