This commit extracts rewriting logic from `ConditionalUpstreamResolver`
into the new `RewriterResolver`, and uses that to enable rewriting for
the `CustomDNSResolver`.
`RewriterResolver` wraps a resolver and applies the rewrite to the
request that is forwarded to the inner resolver.
It also introduces a new optional interface: `NamedResolver`.
This allows a `Resolver` to choose what its user friendly name is,
instead of always being its type name.
