Feature Request: clobber option for FileComponent

[Joe Gottman <jo...@comcast.net>]

FileComponent currently has an append option, which is set to true for File
Producers to make the Producer write to the end of an existing file, and
false to make it overwrite an existing file.  However, sometimes it is an
error for it to do anything to change an existing file.  Would it be
possible to add a clobber option to the FileComponent which defaults to true
but when set to false prevents the File Producer from modifying an existing
file?  It should probably throw some kind of Camel Exception when it
attempts to write to a file that already exists. If desired, the Route can
then catch this Exception and handle it, for instance by trying to write the
file to a different location.

   This option might also be useful for some other Producer components for
the same reason.
