CPU request / limit in the plugin meta.yaml is not correctly translated on the k8s level

[ibuziuk]

Describe the bug

CPU request in the plugin meta.yaml is not correctly translated on the k8s level

e.g. cpuRequest: "30m" is translated to 30 cores (should be either 30m or 0.03):

Che version

• 7.22.0

Steps to reproduce

devfile to reproduce:

metadata:
  name: test-cpulimit22qho
attributes:
  persistVolumes: 'false'
components:
  - type: cheEditor
    reference: >-
      https://gist.githubusercontent.com/sparkoo/cb5105fa1f01f29bf73eb238f6ae622f/raw/090062b9eca6a25ef5226d566ef9626d8a2ca012/theia_meta.yaml
    alias: che-theia
apiVersion: 1.0.0

Details in the

• Adding 'cpuLimit', cpuRequest and memoryRequest to the che-theia plugin meta.yaml che-plugin-registry#716
• Adding 'cpuLimit', cpuRequest and memoryRequest to the che-theia plugin meta.yaml che-plugin-registry#716 (comment)

Expected behavior

cpuRequest: "30m" is transated to either 30m or 0.03

Runtime

• Openshift 4.6

. cpuRequest: "30m" is translated to 30 cores (should be either 30m or 0.003):

@ibuziuk can you explain you math how to get 0.003 from 30m?

It's a bit different from what I can see in code
https://github.com/eclipse/che/blob/75889e8c33601e8986e75bad74456cff39e511c0/infrastructures/kubernetes/src/test/java/org/eclipse/che/workspace/infrastructure/kubernetes/util/KubernetesSizeTest.java#L50

[skabashnyuk]

From what I can see https://kubernetes.io/docs/tasks/configure-pod-container/assign-cpu-resource/#cpu-units
100m=0.1 and 30m=0.03. Yes definitely 30m!=30.
