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.
* Makes all help output showup on stdout like in rubyland
* Moves verbosity flags to capital Vs to get out of the way of version
* Passes version down to mitchellh/cli so it handles -v and --version
flags
* Tweaks version output to remove the leading `v` which is not output
in legacy vagrant
Use the UI provided by the built client instead of creating a
new one. Add support for an extra `v` flag when enabling logging
via flag. An exclude function is added to the logger to prevent
outputting log lines where the content is extremely long for trace
messages. Adding the extra `v` will prevent the suppression and
all log output will be displayed.
