Add new Kubernetes resource kind: "CustomResourceDefinition"

Custom resource definition example in Kubernetes:
  apiVersion: "apiextensions.k8s.io/v1beta"
  kind: CustomResourceDefinition
  metadata:
    name: networks.kubernetes.com
  spec:
    group: kubernetes.com
    version: v1
    scope: Namespaced
    names:
      plural: networks
      singular: network
      kind: Network

Proposed Kubernetes context network definition:
  context:
    custom_resources:
      - name: network        # name of the resource (singular)
        version: v1          # optional, "v1" by default
        scope: Namespaced    # optional, "Namespaced" by default

From this definition, we will extract the Kubernetes parameters:
  - metadata.name: custom_resources.name + "s" + context_name + ".com"
  - spec.group: context_name + ".com"
  - spec.scope: custom_resources.scope
  - spec.version: custom_resources.version
  - spec.names.plural: custom_resources.name + "s"
  - spec.names.singular: custom_resources.name
  - spec.names.kind: custom_resources.name with first capital letter
