Add value hints for health-check property
Add value hints for health-check property

- Add value hints for spring.cloud.deployer.cloudfoundry.health-check
  using additional-spring-configuration-metadata.json.

  and use real values as type
  `org.cloudfoundry.operations.applications.ApplicationHealthCheck`
  is naturally unknown outside of java IDE's.
