The commit before this said "told where to resolve names" and passed --dns,
which is not what it ended up doing. This is that correction: a container is
given the names themselves, written into its own hosts file by the runtime.
The reason for the change is the decision the mesh already made about names — a
file rather than a resolver, because it works on every runtime, needs no
package and has no failure mode of its own. Passing a resolver address would
have required a resolver to exist, which at that point none did.
A resolver is coming, for the case a file genuinely cannot express: a service
named under a machine, postgres.novox.internal, where the wildcard cannot be
enumerated in advance. When it arrives it will need this field back under its
own name. It is not being kept in the meantime — a field nothing fills is a
field nobody can trust, and the vocabulary is asserted by a count for exactly
that reason.
