Change unset-cpu-requirements check

[janisz]

Currently the unset-cpu-requirements requires requests and limits while in general having only requests should be sufficient. Requests are essential for scheduling, and since omitting limits would simply allow the application to utilize a slightly higher amount of CPU if necessary, we should no longer recommend specifying both requests and limits.

The change should happen in check definition

kube-linter/pkg/builtinchecks/yamls/unset-cpu-requirements.yaml

Line 11 in e68f7d1

requirementsType: "any"

As well in related tests:

Line 895 in e68f7d1
