[$] Reducing the bandwidth needs for fwupd

The Linux Vendor Firmware Service (LVFS)
provides a repository where vendors can upload firmware updates that can be
accessed by the fwupd
firmware update daemon on Linux systems. That mechanism allows users to keep
the hardware components of their systems up to date with the latest firmware
releases, but it has gotten so
popular that the daily metadata queries are starting to swamp the LVFS
content delivery network (CDN) server. So Richard Hughes, who developed
fwupd and LVFS, suggested
that it would make sense to start looking at ways to reduce that burden;
the idea was discussed in a recent thread on the Fedora devel mailing list.
