* 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.
