When writing DNS configs, make sure to push the zone file prior to
writing the reference to the zone in the named.conf.options file.
Otherwise, when adding the initial domain (or any subsequent domains,
which isn't really used by these tests), a race occurs between Docker,
writing the updated config files, and the bind daemon, detecting that
mtime has changed on the named.conf.options file and reloading it
and any referenced zone files.
This should fix the error seen in some tests:
> /etc/bind/named.conf:9: parsing failed: file not found

* Export DockerAPI for use by other consumers
As usage of DockerCluster gets more advanced, some users may want to
interact with the container nodes of the cluster. While, if you already
have a DockerAPI instance lying around you can reuse that safely, for
use cases where an existing e.g., docker/testhelpers's runner instance
is not available, reusing the existing cluster's DockerAPI is easiest.

* Add ability to exec commands without runner
When modifying DockerTestCluster's containers manually, we might not
have a Runner instance; instead, expose the ability to run commands via
a DockerAPI instance directly, as they're awfully convenient.

* Add DNS resolver into ACME tests
This updates the pkiext_binary tests to use an adjacent DNS resolver,
allowing these tests to eventually be extended to solve DNS challenges,
as modifying the /etc/hosts file does not allow this.

* Fix bug with DNS configuration validation
Both conditionals here were inverted: address being empty means a bad
specification was given, and the parse being nil means that it was not a
valid IP address.

* Add custom DNS resolver to challenge verification
This required plumbing through the config, reloading it when necessary,
and creating a custom net.Resolver instance.
Not immediately clear is how we'd go about building a custom DNS
validation mechanism that supported multiple resolvers. Likely we'd need
to rely on meikg/dns and handle the resolution separately for each
container and use a custom Dialer that assumes the address is already
pre-resolved.

* Improvements to Docker harness
- Expose additional service information, allowing callers to figure out
both the local address and the network-specific address of the
service container, and
- Allow modifying permissions on uploaded container files.
