There were changes in 'values.yaml' related to SASL to follow Lenses configuration changes on the same context.

• jaasConfig was introduced to set JAAS content inline instead of using a file, remember to not include KafkaClient{} wrapping

  # values.yaml
  lenses:
    kafka:
      sasl:
        enabled: true
        jaasConfig: com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="lenses.keytab" storeKey=true useTicketCache=false serviceName=kafka principal="[email protected]";

• jaasFileData was retained for backward compatibilty reasons but it is marked as deprecated and will be removed in future version.
