  Issue: Support non-dev mode for btp operator log #405

Motivation

When the log from btp operator is sent to a log system, e.g. OpenSearch, it make sense to turn off the dev mode, so the format will be json - which is simpler to process as structured fields

Approach

Use the btp chart with custom values I'll set manager.logger_use_dev_mode to false, so the log will be created in json format
