Question on required 'resources' attribute

[clareliguori]

I noticed that the container resources attribute is marked as required in the spec. Is it intended to be required?
https://github.com/oam-dev/spec/blob/master/3.component_model.md#container

But none of the component schematic examples in this repo have resources configuration:
https://github.com/oam-dev/samples

Similarly there are examples in the Rudr repo without resources config, and the implementation has default values for CPU and memory requirements.
https://github.com/oam-dev/rudr/blob/master/examples/voting/components.yaml
https://github.com/oam-dev/rudr/blob/master/src/schematic/component.rs#L567-L579

Ref #58, #182, and oam-dev/rudr#435.

We sort of ended up with different opinions. Time to revisit it.

We still have an open PR for this: #218
