Title: Fix Vagrant 1.4 compatibility and support multiple SSH keys

Vagrant 1.4.0 added support for multiple SSH keys (mitchellh/vagrant#907) and changed `private_key_path` to an Array.

This PR ensures we always handle it as array to keep compatible with both old and new Vagrant versions. Also pass all of the specified keys to rsync/ssh command.

Fixes #171
