This adds a new libmachine API implementation that skips RPC and instead
uses a vendored in driver directly. This removes the need to download a
separate driver binary. Currently, only the "core" drivers, and kvm are
supported as vendored in. This means that xhyve is the only driver that
requires a separate binary for now.
Libmachine logs can be enabled with --v=3 or higher. --v=7 turns on
debug level info. This will simplify the debugging control plane and
allow us to transition off of libmachine logs in the future.
This introduces the minikube config get/set/unset command. At a basic level, it allows a more user friendly interface for setting minikube config values, but it also allows us to run validations and callbacks before and after the values have been set.
