Add `spring.cloud.kubernetes.enabled` property

See original GitHub issue

It seems like that property spring.cloud.kubernetes.enabled is not provided. On my dev machine I would like to disable k8s aware but it is not possible. I tried this configuration:

spring:
  cloud:
    kubernetes:
      enabled: false # This property does not exist
      secrets:
        enable-api: false
      config:
        enable-api: false
        enabled: false

but when I start my application I have this exception:

I can use maven profiles to exclude Spring Cloud K8S dependencies but I need them for configuration. To confirm the absence of spring.cloud.kubernetes.enabled I also took a look here: https://cloud.spring.io/spring-cloud-static/Hoxton.RELEASE/reference/html/spring-cloud-hoxton-configprops.html and the property is not present.
Thanks
