Removed Values from the Helm Chart

...

• The mzOperator.* values have been moved to operator.*.
• The operator has been made more event-driven and less dependent on frequent periodic synchronizations.
  • As a result, the default synchronization period has changed from 30 seconds to 300 seconds (5 minutes).
    Use the operator.syncPeriod value to set a different synchronization period.

  • Also, if you are using your own service account(s) for your ECD(s), specified via the operator.common.ecd value, then you need to make sure that it has permissions to get and patch the pods/status resource.
