Add a method, getContentAsString, to ContentCachingRequestWrapper. Having a method directly on ContentCachingRequestWrapper allows delegating to the toString(Charset) method of ByteArrayOutputStream, avoiding an extra copy that calling getContentAsByteArray and then converting to a String would.
In practice I've seen a lot of usages of ContentCachingRequestWrapper where getContentAsByteArray is called and the returned bytes are immediately decoded to a String; this method would allow a user to avoid the overhead of the extra copy that incurs.
