Add Support for Kubernetes Service Catalog

[salaboy]

We should support the interaction against the Kubernetes Service Catalog, @iocanel has an implementation already that we can test and align with this projects: http://iocanel.com/2018/09/service-catalog-pt-2/

You probably won't be surprised @salaboy that I'm interested in hearing your ideas about this as well :)

Would this not be a separate component to support the spring cloud connectors projects?

[spencergibb]

We have no plans to update spring cloud connectors

If anything it might end up looking like https://github.com/pivotal-cf/java-cfenv

See https://github.com/buildpack/rfcs/blob/master/text/0012-service-binding.md#structure for potential structure.

@ryanjbaxter isn't this something you already added?
