commit d508ffc51b3631ea1c1057f93c534903f23c394f
Author: Sam Thursfield <sam afuera me uk>

functional-tests: Add miner-power test
This test uses [umockdev] to verify that the miner-fs pauses when upower
reports a low battery condition.
The umockdev dependency is optional and the test will report as being
skipped if umockdev isn't available.
Depends on https://gitlab.gnome.org/GNOME/tracker-oci-images/-/merge_requests/23
and https://gitlab.gnome.org/GNOME/tracker/-/merge_requests/254
[umockdev]: https://github.com/martinpitt/umockdev
