Support DOMAction-level routing
We have a distinct use case where we want to route actions across
a system. In this scenario, a next hop provider registers itself as the
local provider with the appropriate cost.
This capability is also exposed as the simplest way of registering
binding-level implementations -- where we want to register to all
actions on the operational datastore.
Add explicit documentation around how how the arguments are interpreted
and teach DOMRpcRouter about wildcards -- similar to how it deals with
RPCs.
