Strimzi User Operator failing after 0.27.1 upgrade

[keyurbitw]

Bug Description

I am using a standalone strimzi operator to connect to my Kafka cluster. Recently I updated the Strzimi Operator from 0.26.1 to 0.27.1. Post the upgrade the user operator is failing giving the below error:

2023-06-08 04:02:41 DEBUG AbstractOperator:610 - Reconciliation #543(watch) KafkaUser(alerting/alert.user): Removed metric strimzi.resource.statealerting:KafkaUser/alert.user
2023-06-08 04:02:41 DEBUG AbstractOperator:618 - Reconciliation #543(watch) KafkaUser(alerting/alert.user): Updated metric strimzi.resource.state[tag(kind=KafkaUser),tag(name=alert.user),tag(reason=Cluster authorization failed.),tag(resource-namespace=alerting)] = 0
2023-06-08 04:02:41 WARN AbstractOperator:532 - Reconciliation #543(watch) KafkaUser(alerting/alert.user): Failed to reconcile
org.apache.kafka.common.errors.ClusterAuthorizationException: Cluster authorization failed.
2023-06-08 04:02:41 DEBUG AbstractOperator:440 - Reconciliation #543(watch) KafkaUser(alerting/alert.user): Lock lock::alerting::KafkaUser::alert.user released

I see the same error for most of the users. The strange part is once I restart the useroperator I dont see this error for some time and again once the periodic reconciliation starts I start seeing this error again.

The older version 0.26.1 works fine on the same setup.
