Brian Cain 4bd95cbfe2 (#8864) Improve vagrant validate command
Prior to this commit, the `vagrant validate` command would only validate
the first machine in a vagrant file. This commit improves that by
validating all known machines in the environment. If one is not found,
it will properly throw an exception instead of a stacktrace.
