Subject: [PATCH 02/11] Add unique names to all tmpdir and tempfile calls in
 tests + cleanup

This commit attempts to uniquely identify the temporary files and
directories that are created during test runs. Where it was a quick
fix, this commit also removes the temporary files and directories.

There are still a ton of temporary files due to calls to
.isolated_environment in the tests without an easy API an easy way
to provide a closer to that function.

Subject: [PATCH 03/11] Do not create a tempfile when downloading box metadata

The only reason we were using Tempfile was to generate the path. This
commit switches to using `Dir::Tmpname.create`, which accomplishes the
same thing without the overhead of creating and removing a tempfile.

Subject: [PATCH 04/11] Give a unique, prefixed name to all tempfiles

This commit basically grepped the code base for all uses of Dir.mktmpdir
and Tempfile.new/open and ensures the value is unique within the
code base and also prefixed with `vagrant-`.

Previously, most invocations of these commands simply used "vagrant",
thus making them indistinguishable when trying to identify leaks.

Subject: [PATCH 05/11] Use Util::Tempfile when configuring networks

This fixes a fairly large tempfile leak. Vagrant uses a template
renderer to write network configuration files locally to disk. Then,
that temporarily file is uploaded to the remote host and moved into
place. Since Vagrant is such a short-lived process, GC never came along
and cleaned up those tempfiles, resulting in many temporary files being
created through regular Vagrant usage.

The Util::Tempfile class uses a block to ensure the temporary file is
deleted when the block finishes. This API required small tweaks to the
usage, but provides more safety to ensure the files are deleted.
