Description

See nabble
http://camel.465427.n5.nabble.com/File-Component-Rename-an-existing-file-tp5716075.html

We should add new moveExisting enum to fileExist option, so end user can configure Camel to move any existing file before writing a new file.

That would need a corresponding option to set the expression for the new name to use.

For example to append .old to the existing name
moveExisting=${file:name}.old

The trick would be if there is already an .old file. In that case Camel should fail with an exception.
