Hello,

Thank you @lotusnoir and @benoit-garcia for your job.

@benoit-garcia Can you validate this Pull request ?

I want to create S3 bucket but tag usage it's an important thing.
I try to avoid to fork all Scaleway module to avoid to recreate the wheel each time.

Regards,

Hello,

@jgalais
I've added support of tags on v2.0.0. Feel free to test and let me know.

@lotusnoir
Thanks for you work. I'd like to maintain some consistency on code style.
As I couldn't edit your pull request, I create #34 based on your code and improved/cleaned it a little.
Hope you won't mind; your contributions are highly appreciated.
