[Kuryr] Proposing Roman Dobosz for kuryr-kubernetes core

Hello,

I'd like to propose Roman for the core reviewer role in kuryr- kubernetes. Roman was leading several successful development activities during Train and Ussuri cycles:

* Switch to use openstacksdk as our OpenStack API client. * Support for IPv6. * Moving VIF data from pod annotations to a KuryrPort CR.

He also demonstrated code reviewing skills of an experienced Python developer.

In the absence of objections, I'll proceed with adding Roman to the core team next week.

Thanks, Michał
