MEDIUM: proxy_protocol: Support sending unique IDs using PPv2

This patch adds the `unique-id` option to `proxy-v2-options`. If this
option is set a unique ID will be generated based on the `unique-id-format`
while sending the proxy protocol v2 header and stored as the unique id for
the first stream of the connection.

This feature is meant to be used in `tcp` mode. It works on HTTP mode, but
might result in inconsistent unique IDs for the first request on a keep-alive
connection, because the unique ID for the first stream is generated earlier
than the others.

Now that we can send unique IDs in `tcp` mode the `%ID` log variable is made
available in TCP mode.
