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.
Default the options for default provider so an options value is not
required when calling. The index for the proc lookup should use the key
method, not index.
- Pulls in the SDK changes to Project.DefaultProvider and Project.Target
- Implements the hefty default provider method
- Un-hard-codes provider from Target, and sets it when a Target is
looked up from a Project
