Feature Request: Add support for setting resource requests and limits

[JoeKer1]

When using this in GKE the default resource requests and limits are often higher than the deployment I'm trying to sleep. So with nothing set for resource requests or limits in GKE snorlax's deployment uses 2cpus and a 1g of ram.

Would it be possible to add that configuration to the sleep schedule or a configmap? I have not done much goLang but I can give it a shot.
