  -----------
  director: Add director_output_buffer_size setting

This allows configuring the max buffer size for outgoing connections.
Previously it was hardcoded to 10 MB, which wasn't necessarily enough for
very busy directors.

  Log Message:
  -----------
  director: Close director connection immediately when output buffer is full

Only the ostream was closed, which didn't actually cause the disconnection
until the other side closed the connection.

  -----------
  director: Fix updating director connection's last_output timestamp

It was previously updated only in ostream's flush callback, which was called
only when there were a lot of output. This only caused the "last output"
timestamp in disconnection log lines to be wrong.

  Log Message:
  -----------
  director: Show each director connection in doveadm DIRECTOR-LIST

Previously the host was shown only once, regardless of how many connections
it had. This especially helps when there are just two directors, but also
can be useful when showing incoming/outgoing connections that are still
in handshaking phase.
