Adds initial basic support for HCP based configuration in vagrant-go. The initalization process has been updated to remove Vagrantfile parsing from the client, moving it to the runner using init jobs for the basis and the project (if there is one). Detection is done on the file based on extension for Ruby based parsing or HCP based parsing. Current HCP parsing is extremely simple and currently just a base to build off. Config components will be able to implement an `Init` function to handle receiving configuration data from a non-native source file. This will be extended to include a default approach for injecting defined data in the future. Some cleanup was done in the state around validations. Some logging adjustments were applied on the Ruby side for better behavior consistency. VirtualBox provider now caches locale detection to prevent multiple checks every time the driver is initialized.
Vagrant Core Plugins
These are plugins that ship with Vagrant. Vagrant core uses its own plugin system to power a lot of the core pieces that ship with Vagrant. Each plugin will have its own README which explains its specific role.
