ari: Add a copy operation for stored recordings

This patch adds a new operation for stored recordings, copy. It takes an
existing stored recording and makes a copy of it in the same directory
or a relative directory under the stored recording directory.

/ari/recordings/stored/{recordingName}/copy?destinationRecordingName={copy_name}

This is particularly useful for voicemail-esque applications, which may need to
copy or move recordings around a directory structure.
