operator: Increase resource limits to 1.5 CPU

[travisn]

The operator needs to burst significantly when reconciling, then will quiet down and nearly not consume any cpu. Therefore, we allow the operator to burst to 1.5 cpu instead of limiting it to a 0.5 cpu.

should we update examples here

rook/deploy/examples/operator.yaml

Lines 671 to 678 in e8002a6

	# Recommended resource requests and limits, if desired
	#resources:
	# limits:
	# cpu: 500m
	# memory: 512Mi
	# requests:
	# cpu: 100m
	# memory: 128Mi

and similar in operator-openshift.yaml files?

sounds like a good idea to me!

Good catch, thanks

Seems good to me. I feel like it could be worth doing some golang profiling on the operator when it's running to see if there are any places in the code that are particular resource hogs. But also, 1.5 CPUs isn't a ridiculous amount IMO.
