Add resource requirements check to doks group

[varshavaradarajan]

The resource-requirements check is in the basic group right now. However, many of doks users face resource contention issues because they may not have followed this best practice of setting resource limits on their pods. We currently run all the checks in the doks group before an upgrade. We can show this warning to users if this check is added to the doks group as well.

Hello @varshavaradarajan! I can try this out

Any pointers for this?

@fish-dango - thanks for your interest! :) The resource-requirements check is already added to the basic group here: https://github.com/digitalocean/clusterlint/blob/master/checks/basic/resource_requests.go#L40, you can add doks to the slice there.
