Aurelien DARRAGON ad0133cc50 MINOR: log: handle log-forward "option host"
Following previous patch, we know implement the logic for the host
option under log-forward section. Possible strategies are:

      replace If input message already contains a value for the host
              field, we replace it by the source IP address from the
              sender.
              If input message doesn't contain a value for the host field
              (ie: '-' as input rfc5424 message or non compliant rfc3164
              or rfc5424 message), we use the source IP address from the
              sender as host field.

      fill    If input message already contains a value for the host field,
              we keep it.
              If input message doesn't contain a value for the host field
              (ie: '-' as input rfc5424 message or non compliant rfc3164
              or rfc5424 message), we use the source IP address from the
              sender as host field.

      keep    If input message already contains a value for the host field,
              we keep it.
              If input message doesn't contain a value for the host field,
              we set it to localhost (rfc3164) or '-' (rfc5424).
              (This is the default)

      append  If input message already contains a value for the host field,
              we append a comma followed by the IP address from the sender.
              If input message doesn't contain a value for the host field,
              we use the source IP address from the sender.

Default value (unchanged) is "keep" strategy. option host is only relevant
with rfc3164 or rfc5424 format on log targets. Also, if the source address
is not available (ie: UNIX socket), default behavior prevails.
