build-sources-list.install: automatically import the ubuntu-esm ppa key
Automatically pull the ubuntu-esm ppa gpg public key from the ubuntu
keyserver and place it into the /etc/apt/trusted.gpg.d/ directory; also,
rework the script to use variable definitions for file locations and the
key fingerprint, plus also explain what the script is doing a little
more.

build-sources-list: disable including partner at all
The Canonical partner archive <https://archive.canonical.com/partner> is
not meaningfully supported anymore, and archive metadata is not created
for new releases anymore, so drop creating it from the apt sources we
use for umt.

umt autopkgtest: use local mirror if configure in ~/.ubuntu-security-tools.conf
When creating autopkgtest images, set the image to point at
your local ubuntu archive mirror if you have one configured in
~/.ubuntu-security-tools.conf in build_tools_sbuildmirror.
A TODO item here is to make this work with non amd64 architectures,
which use the ports archive and can be mirrored or not-mirrored
separately.
