add an option to maildir handler to enable you to specify a particular
ssh identity file, defaulting to the expected /root/.ssh/id_rsa. This is important to have if you are trying to backup to a different user on a backuphost than other handlers are using. For example, if the rdiff handler is connecting to backalbatross@backupserver-pn using /root/.ssh/id_rsa for public key authentication, and you want to configure the maildir handler to connect as user backmaildir@backupserver-pn you will might want to specify a different identity file for that authentication (if you do not want to share the id file between the 'backalbatross' and 'backmaildir' users). Note: this cannot be accomplished with a ssh config file because that file is host based, ie. you can only specify one user per host specified in the config
