Add check for update strategy

[joshiste]

There is no check on the update strategy.

To avoid interruptions during updates of deployments/statefulsets it's advisable to use a rolling update strategy.
I think it is reasonable to add this check if the pods are targeted by a service to check for the update strategy.

KubeLinter has this check. Let me know what you think. If you find this acceptable, I'd happily contribute a PR.

Yes, this makes sense for Deployments. Add a warning if the strategy is "Recreate" and the Deployment is targeted by a Service.
