* I had to contextualise Communicator.Start and RemoteCmd.StartWithUi
NOTE: Communicator.Start starts a RemoteCmd but RemoteCmd.StartWithUi will run the cmd and wait for a return, so I renamed StartWithUi to RunWithUi so that the intent is clearer.
Ideally in the future RunWithUi will be named back to StartWithUi and the exit status or wait funcs of the command will allow to wait for a return. If you do so please read carrefully https://golang.org/pkg/os/exec/#Cmd.Stdout to avoid a deadlock
* cmd.ExitStatus to cmd.ExitStatus() is now blocking to avoid race conditions
* also had to simplify StartWithUi
this regroups the calls of tmp func calls into one package.
the tmp pkg allows to store tmp files under a common directory for easier managment

We can't modify the destination path in the communicator because it
breaks assumptions in the provisioners. For example, we try to chmod in
the shell provisioner. The chmod command uses the path as supplied by
the user. If the communicator decides to rewrite the path, the
provisioner doesn't know that, and so tries to chmod the wrong thing.
The best we can do is detect that the destination is a directory and
fail.
Also correctly surface output from sftp uploader.
Surfaces any communications from the remote end during file
uploads. For example, we might get notifications if we're logging in
with the wrong user. Rather than swallow these, let's show them to the
user.
RequestPty from crypto/ssh looks like this:
func (s *Session) RequestPty(term string, h, w int, termmodes TerminalModes) error
So arguments 2 and 3 are height and width, respectively. I'm not sure if
the original was just a typo, or if there's an actual reason we want a
40 column terminal. Either way, having a terminal this narrow led me to
a really "fun" bug[0], where `wget` in my shell provisioner scripts
would segfault when trying to display the progress bar.
