Remove CRUD for Receptor Addresses

Removes ability to directly create and delete
receptor addresses for a given node.

Instead, receptor addresses are created automatically
if listener_port is set on the Instance.

For example patching "hop" instance

with {"listener_port": 6667}

will create a canonical receptor address with port
6667.

Likewise, peers_from_control_nodes on the instance
sets the peers_from_control_nodes on the canonical
address (if listener port is also set).

protocol is a read-only field that simply reflects
the canonical address protocol.

Other Changes:

- rename k8s_routable to is_internal
- add protocol to ReceptorAddress
- remove peers_from_control_nodes and listener_port
from Instance model
