Add rolloutStategy parameter to ImageRegistrySpec

[Fedosin]

To allow us to define a rollout strategy for the image registry deployment, we create an additional parameter in ImageRegistrySpec.

@sttts can we make this a appsv1.DeploymentStrategyType [1]? Would we automatically get the validation pattern we want?

If not, then the validation pattern needs to be added as a comment tag - see [2] as an example.

done!

[sttts]

@adambkaplan upstream types are coded (and validated) in Go. There is no connection to these validation here and those in Go land.

Thanks for the review!
