- Do not load existing ACME challenges persisted within storage on non-active nodes. This was the main culprit of the issues, secondary nodes would load existing persisted challenges trying to resolve them but writes would fail leading to the excessive logging.
- We now handle this by not starting the ACME background thread on non-active nodes, while also checking within the scheduling loop and breaking out. That will force a re-reading of the Closing channel that should have been called by the PKI plugin's Cleanup method.
- If a node is stepped down from being the active node while it is actively processing a verification, we could get into an infinite loop due to an ErrReadOnly error attempting to clean up a challenge entry
- Add a maximum number of retries for errors around attempting to decode,fetch challenge/authorization entries from disk. We use double the number of "normal" max attempts for these types of errors, than we would for normal ACME retry attempts to avoid collision issues. Note that these additional retry attempts are not persisted to disk and will restart on every node start
- Add a 1 second backoff to any disk related error to not immediately spin on disk/io errors for challenges.

- We've seen a few issues with bind's auto-loading of configuration
too quickly at bad times leading to it having partial configurations
or not all files/permissions being restored properly during it's read
attempt.
- See if the freeze/thaw rndc commands will help out with these timing
issues
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

* 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.
