main: add new upload command

This commit adds a new `upload` command that can be used to
upload a raw image to the cloud. Currently only AWS is
supported but as images adds more clouds to the uploader interfac
we can easily expand more.

The cloud is currently detected via the file extension, that
mapping probably should also go into the `images` library.
