Add possibility to save ByteMessage content in the sample result.

**mchassagneux** ([Bug 54434](https://bz.apache.org/bugzilla//show_bug.cgi?id=54434&redirect=false)):
Since https://github.com/apache/jmeter/issues/2991, JMeter is able to handle ByteMessage for JMS sample.
But when I read a message in this format, the content is not save, I can just read this message :

"XX bytes received in BytesMessage"

So, could you please add in the sample result object, the real content of the ByteMessage like this :

// copy data into a byte[] array
int dataSize = (int) msg.getBodyLength();
byte[] array = new byte[dataSize];
msg.readBytes(array , dataSize);

[...]

result.setResponseData( array );

The goal of this, is to send later the message (or save into a file )

Thanks !
