Is your feature request related to a problem? Please describe

The official Helm chart includes an example of the resources limits/requests:

garnet/charts/garnet/values.yaml

Lines 117 to 124 in d7d2bc6

	# -- Resources
	resources: {}
	# limits:
	# cpu: 200m
	# memory: 64Mi
	# requests:
	# cpu: 10m
	# memory: 16Mi

but, there is no explanation of those are defaults or recommended values or just 'syntactical' placeholders.

Describe the solution you'd like

At least a suggestion of minimum and recommended limits/requests should be documented to give users an idea, bearings.

Ideally, if Garnet's chart could specify the resources requirements with pre-defined presets like this chart does it for Redis providing
none, nano, micro, small, ... presets:
