FileConsumer should allow files to be processed more than once when "noop" setting is used.

                 Key: CAMEL-1928
                 URL: https://issues.apache.org/activemq/browse/CAMEL-1928
             Project: Apache Camel
          Issue Type: Improvement
          Components: camel-core
    Affects Versions: 2.0-M3
            Reporter: Alexander Lee
            Priority: Minor


If the "noop" setting is used with the FileConsumer, then this forces use of the idempotent
repository.  This means that files are only ever picked up once.  While this is probably the
desired behaviour for most users, it makes it difficult to use the files to generate events
on a timed basis.   For instance, a file could be used to store query configuration which
was read every hour and used to query a database, the data from which would be added to an
exchange and sent to the next step.  In this case we don't want to delete or move the original
file and we want to read it again.

At the moment this behaviour can be simulated by using "preMove" to move the file to a new
extension, and then "move" to move it back.  It would be better if there was a way to default
use of the idempotent repository as is the case now, but also provide a way to explicitly
turn it off if required.
