The length of an error message triggered due to a command to the Controller should not be limited

Current Situation

If a command to the Controller is faulty, then the error message returned must not be longer than 10000 bytes. If this length is exceeded, the following message is logged in the joc.log.

j.p.ControllerApi - akka.http.scaladsl.model.EntityStreamException: Request too large: Request of size 31791 was longer than the maximum of 10100

The "real" error is written to the controller-debug.log file.

Desired Behavior

The length of an error message triggered due to a command to the Controller should not be limited. Long messages should be truncated after 8M.
