This commit makes the Docker cli client use ValidateContextDirectory
before attempting to create a tarball out of the context. This ensures
we avoid errors such as "unexpected EOF" during the upload of the
context.
This check is done before uploading any data and can save time and
bandwidth for remote Docker daemons.
