Upload file from string or file-like object

[giovannipizzi]

The method simple_upload(self, machine, sourcePath, targetPath) requires the source file to be an actual file on disk. There are cases (e.g. uploading a simple short text file) where the content is in memory (in a string, or in a file-like object - e.g. an already open file). Would it be possible to support passing the content or a file-like object, or this is complicated? (For now, I need to create a NamedTemporaryFile to upload the content, is this the suggested approach?)

Similarly, I just realised that in simple_upload, the targetPath must be a folder (and the file will get the same filename as the source file). Is it possible to specify instead the destination filename? (This actually prevents even using a NamedTemporaryFile, I have to use a TemporaryDirectory and create a file with the correct name, and then transfer to the folder).

Even if there is no plan to change it, I suggest to clarify the docstring (now it says targetPath: the absolute target path that I would interpret as the path of the destination file)
