[Dovecot] Proxy: %$ should contain username

[Reindl Harald]

for nomal operations

 * login_log_format_elements = %r %m %k
 * login_log_format          = %$: %s

would be perfect because "proxy(h.reindl at thelounge.net)" contains the username
*but* in case of auth errors "Disconnected (auth failed, 1 attempts in 2 secs)"
does not show the username - hence currently there exists no way to avoid
username double-logging in normal operations without render the log unusebale
in case auf dictionary attacks / authentication failers

another option would be make %$ obsolete because i do not need to see
"proxy(h.reindl at thelounge.net): started proxying to 127.0.0.1:143"
because i know that *but* in case of auth errors "%s" doe snot
contain any hint of a error and would show "user=<h.reindl at thelounge.net>,
10.0.0.241, CRAM-MD5, TLS" even with a wrong password and nothing else

that is not really optimal, in case of "tail -f" someone does not want redundant
informations leading to linebreaks as well it wastes disk space
