A new constructor has been added to the TikaController to provide
the new spring config.
The creation of the TikaExecutor has been moved to "singleton pattern" as
the injection of the @Value happens after the instantiation of the
TikaJavaExecutor and does not pass the value correctly. The
instantiation is now done once, on the first transform request.
Param has been added to the AIO beans.
