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.
Changes:
- added cache.cacheTimeNegative (time.Duration)
- if not configured the default cache time stays at 30 min
- if set to a value below zero caching of negative responses is disabled
When an address is blocked, it can be cached by the client. If we
then wish to allow that address, or just disable the blocking
feature, that client is not gonna be able to see that domain until
the previous domain expires.
The units of time for this setting is in seconds, since we might
want to set it to values around 5 or 10 seconds, depending on the
scenario. The default value for it is the value used before, so
ignoring this setting wont result on any change.
