Vagrant is a tool for building and distributing development environments.

VagrantPlugins::ProviderVirtualBox::Action::SaneDefaults#attempt_and_log

This is just a helper method that executes a single command, logs
the given string to the log, and also includes the exit status in
the log message.

We assume every command is idempotent and pass along the `retryable`
flag. This is because VBoxManage is janky about running simultaneously
on the same box, and if we up multiple boxes at the same time, a bunch
of modifyvm commands get fired
