feat: pass manager kwargs from namespace

[devamin]

WHY

I need to pass ignore_queue from namespace emit call.

WHAT

Pass kwargs from namespace emit to server emit

[miguelgrinberg]

Thanks, this looks good in principle, but passing kwargs is not a good solution, as it makes it much harder to properly document these calls. So I would like to request two things:

1. Add any missing function arguments explicitly
2. Update the docstrings accordingly

Do you think you can make these changes? Thanks!

[devamin]

You welcome, thanks for you for creating this library. Yes I can handle these requirements.

@miguelgrinberg please let me know if all good, or there is something that I need to change/add.

[miguelgrinberg]

Thanks. There were a few missing things in this PR such as the same support for ignore_queue in send() and call(), and also the tests needed some updates to cope with these changes. I have committed a complete fix now.
