Depending on different external URLs makes our provisioning scripts flaky,
because they can fail if any one of the external servers goes down.
In this patch
* the docker images qt_ubuntu_16.04 and qt_ubuntu_18.04 are being built first,
they apt-get from the internal ubuntu mirror
* all the existing docker images have been rebased to these two images, so
they inherit this behavior
* images that fetch files from the internet have been modified to not do the
fetching themselves; insted URLs are fetched in advance using "DownloadURL"
which accepts internal mirrored URLs, and the downloaded files are ADDed to
the images with a local copy
* previously existing git clone commands have been modified to fetch
internally mirrored tarballs
