Archive mirrors in LXD containers

@sergiusens

To keep containers sane, we need to select a proper archive mirror depending on the location of the snapcraft user.

When using snapcraft cleanbuild or SNAPCRAFT_CONTAINER_BUILDS=1 snapcraft the LXD container uses default sources regardless of what’s setup on the host. Defaults can be painfully slow in some locations where a local mirror is required.

• Ideally snapcraft could be smart out of the box and figure out what’s being used on the system
• We probably also want a config option for this or an environment variable

I agree, and I wonder the --enable-geoip option in snapcraft cleanbuild means?

It means that Snapcraft will try to use a local mirror for stage-packages that may be faster.
