Create remote_port field

[CleitonDeLima]

I wonder if it wouldn't be interesting to keep a record of the port in the logs, in some cases it might be useful to keep this information.

In the middleware it is ignored.

Yes, I think it would be useful sometimes to keep the port in remote_addr field.

As the library removes the port, we need a config to disable this behavior. the config shouldn't be enabled be default to prevent breaking changes.

Currently the IP value of the X-Forwarded-For header is taken. The port is removed in the middleware in a specific case. My idea is to create a new field remote_port (PositiveIntegerField) to save the port of the X-Forwarded-Port header that some servers configure.

This new field would only receive a value through a settings.

If it is a valid idea, I can make a PR.

This also works. please remember to set the new field nullable to won't break the current system.

Then we don't need the config. because adding a new nullable field won't break anything.

Great!
