Replaces `startVerifyUpstream` and behaves just like
`blocking.loading.strategy`.
We use the bootstrap resolver for any requests that arrive before the
upstreams are initialized.

- `CacheControl.FlushCaches`
- `Querier.Query`
- `Resolver.Resolve`
Besides all the API churn, this leads to `ParallelBestResolver`,
`StrictResolver` and `UpstreamResolver` simplification: timeouts only
need to be setup in one place, `UpstreamResolver`.
We also benefit from using HTTP request contexts, so if the client
closes the connection we stop processing on our side.
* refactor: make `config.Duration` a struct with `time.Duration` embed
Allows directly calling `time.Duration` methods.
* refactor(HostsFileResolver): don't copy individual config items
The idea is to make adding configuration options easier, and searching
for references straight forward.
* refactor: move config printing to struct and use a logger
Using a logger allows using multiple levels so the whole configuration
can be printed in trace/verbose mode, but only important parts are
shown by default.
* squash: rename `Cast` to `ToDuration`
* squash: revert `Duration` to a simple wrapper ("new type" pattern)
* squash: `Duration.IsZero` tests
* squash: refactor resolvers to rely on their config directly if possible
* squash: implement `IsEnabled` and `LogValues` for all resolvers
* refactor: use go-enum `--values` to simplify getting all log fields
* refactor: simplify `QType` unmarshaling
* squash: rename `ValueLogger` to `Configurable`
* squash: rename `UpstreamConfig` to `ParallelBestConfig`
* squash: rename `RewriteConfig` to `RewriterConfig`
* squash: config tests
* squash: resolver tests
* squash: add `ForEach` test and improve `Chain` ones
* squash: simplify implementing `config.Configurable`
* squash: minor changes for better coverage
* squash: more `UnmarshalYAML` -> `UnmarshalText`
* refactor: move `config.Upstream` into own file
* refactor: add `Resolver.Type` method
* squash: add `log` method to `typed` to use `Resolover.Type` as prefix
* squash: tweak startup config logging
* squash: add `LogResolverConfig` tests
* squash: make sure all options of type `Duration` use `%s`
This makes iterating with breaking refactors easier as you can also
break the mocks without breaking normal compilation.
Also unexport code only used in the resolver package.
Only `MockUDPUpstreamServer` is kept as non test and exported as it is
used by the server package.
* go test -> ginkgo
* removed flake-attempts as suggested
* added FlakeAttempts to flaky test definition
* as net.DNSError qualifies as net.Error check and correct the response
* fix in downloader.go resolves flaky tests
* unwrap maybe?
* excluede DownloadFile from funlen linter
* use eventually on io operations in file_writer_test
* file_writer_test flaky fixes
* fix linter errors
* Serve test reversed go routine
* matcher fix
* serve test rework 2
* DeferCleanup tmp files
* fixed some flakiness in resolver tests
* go mod tidy
* fixed linter errors
* JustAfterEach -> DeferCleanup
* changed close to defer
* moved unwrap from downloader to test
* fix linter error
* propper cleanup in "should return error"

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.
* comama seperated client names
(cherry picked from commit cdb009d0c8e14b2be25b6a8beb563017c603f674)
* blocking_resolver unittest
(cherry picked from commit cb059deb282bcc614939dc021041c0b35665a84e)
* linter errors reduced
* unit test for group merge
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.
