Adding request extra to support value like "nvidia.com/gpu: 1"

[pjeon2]

Current helm chart only supports cpu and memory, so I would like to add extra field
For example, I need to add below values

            requests:
              cpu: 10m
              memory: 16Mi
              nvidia.com/gpu: "1"

To support the above values, I added resources.extra field

Closes #901.

Thanks for the PR @pjeon2. I've added a couple of generic review comments which would need addressing before this PR could be tested.

However that said I'm not sure if the explicit capacity.resources.cpu & capacity.resources.memory are required as capacity.resources could be untyped and directly used with toYaml. What do you think?

Yeah, I think converting entire capacity.resources to toYaml is better approach.
I will apply it into my PR

@stevehipwell I resolved all your comments.
Would you review it again?

I've suggested an update to the value comment for consistency; you'll need to re-run helm-docs after changing this.

Could you also update the changelog under the unreleased section.
