It shouldn't be necessary to deploy the app on proxy reboot. When there
are multiple apps using the same proxy we'll only deploy the one we
run the reboot command from, so we don't always reboot anyway.
Instead of checking for the proxy key, we'll set the config to {} if it
is nil in the Kamal::Configuration::Proxy initializer.
This is a bit cleaner, and maybe it will help with
https://github.com/basecamp/kamal/issues/1555 if somehow
@raw_config.key?(:proxy) is false but @raw_config.proxy is not nil.
When booting non-primary role hosts we will always wait for a primary
role host to boor first.
So when booting in groups, if there are no primary role hosts in the
first batch, then booting will stall.
Sort primary role app_hosts first to avoid this.

Allow --metrics_port and --debug options to be set via the boot config.
--metrics_port support will come in kamal-proxy v0.8.8, so this option
doesn't work right now.
This will be updated before the next Kamal release though and we can add
integration tests for the metrics at that point.
This is for boot time configuration for the kamal proxy. Config in here
doesn't not belong in Kamal::Configuration::Proxy which is for deploy
time configuration for the app itself.
Kamal apps don't contain boot time config, because multiple apps can
share a proxy and the config could conflict.
We'll set the KAMAL_LOCK environment when calling run hooks. If set to
true we have the lock and the hook will not need to acquire it again if
it runs kamal commands.

Docker buildx build outputs the build logs to stderr by default.
SSHKit displays stderr logs in red, which can suggest that an error has
occurred.
Redirect the output to stdout, so it shows in green. If there is an
error, the output will be repeated in red anyway.

The `app exec` and `accessory exec` commands will run `docker run` if
they are not set to reuse existing containers. This might need to pull
an image so let's make sure we are logged in before running the command.

We hook into the SSHKit `on` method to run the pre-connect hook before
the first SSH command. This doesn't work for interactive exec commands
where ssh is called directly.
