Initial support for agentless (#1267)

Add initial support for the basic service mesh running with agentless.

* Update connect-inject deployment to talk to consul servers (currently only in-cluster servers are supported; external servers support will come in a later PR)
* Update endpoints controller to register and deregister services and health checks in the catalog and stop using agent APIs
* Update connect-init command to take the -node-name flag so that it can search for services within a given node using catalog APIs
* Add k8s probes to the envoy container
* Provide -node-name flag to the consul connect envoy command so that we can generate correct configuration
* Selectively disable acceptance tests that don't yet work in this configuration
* Disable consul clients by default
