In cases where processing a folder failed, but a retry might well succeed
e.g. when the server connection had simply timed out and was disconnected,
we can throw a FOLDER_RETRY (which is less severe than FOLDER).

This Exception can be thrown whenever a sync error occurs. It is used
for outputting sensible error messages to the user and it denotes a
"severity", it can tell offlineimap if we need to abort a message, a
folder, a repo sync, or whether we should indeed abort immediately.
The exception is not yet used in the code.
