Provided that the SmartSource headers are being
saved to file, and that the path to those files
is present in the survey configuration, we now
import SmartSource information as metadata in
raw_shots.meta->'smsrc'.
Closes#19.
This script runs the deferred imports. It is meant to
be called from a cronjob at regular intervals – every
one or two minutes is probably a good setting.
It checks if another instance is already running before
doing its thing.
If anything goes wrong (any of the called processes exits
with non-zero condition) it will send an alert to GitLab,
provided that the authorisation key is known.
