Fix cockroachdb not abiding by resources reqs (#5629)

The containers in the stateful set were ignoring the resource requests
when specified in `values.yaml`. Comment out the resources requests
in `values.yaml`, so we only set requests if the user specifically
enables them.

I verified this is working by running `kubectl describe pod POD | grep
cpu` on one of the created pods on the fix branch. It returned `cpu:
"100m"`. On the master branch, the same command returned nothing.
