* 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.
