doveadm proxy list repeats header line

[Michael Goth]

Hi all,

just a minor thing: Why does `doveadm proxy list` repeat the header line 
after each entry? Too me, that just makes the output harder to read.

So instead of this:

root at mail1 ~ # doveadm proxy list
username            proto   src ip        dest ip         port
info at domain1.de     imap    80.152.196.98 222.133.127.53  993
username            service src-ip        dest-ip         dest-port
info at domain1.de     imap    80.152.196.98 222.133.127.53  993
username            service src-ip        dest-ip         dest-port
info at domain1.de     imap    80.152.196.98 222.133.127.53  993
username            service src-ip        dest-ip         dest-port
tj at domain1.de       imap    83.149.131.71 222.133.127.53  993
username            service src-ip        dest-ip         dest-port
tj at domain1.de       imap    83.149.131.71 222.133.127.53  993


I'd prefer this:

root at mail1 ~ # doveadm proxy list
username            proto   src ip        dest ip         port
info at domain1.de     imap    80.152.196.98 222.133.127.53  993
info at domain1.de     imap    80.152.196.98 222.133.127.53  993
info at domain1.de     imap    80.152.196.98 222.133.127.53  993
tj at domain1.de       imap    83.149.131.71 222.133.127.53  993
tj at domain1.de       imap    83.149.131.71 222.133.127.53  993


The repeated header lines also happen with other formatters.
