Fix the Limits

I don't want the pod to be consuming too much of your machine's resources, nor do I want you to have a constantly crashing pod, so before moving on, let's just reduce the memory usage of the testram pod.

Set the MEGABYTES environment variable to 10 and apply the change, then delete the pod so that the new environment variable takes effect.

Use get pods and top pods to make sure the pod is healthy and is using around 10 megabytes of memory.
