CI: new data bootstrapped image

The idea is that the initialization that occurs so far
in all our CI jobs is lengthy and resource intensive: it accounts
to about 5 minutes per job.

For true installations, it makes sense to perform these steps with
an initial configuration that's already as intended. But for our
tests, the result is always the same for a given base image.

Because the affected directories are volumes, we need to copy the
result elsewhere on the filesystem, so that they aren't discarded

In turn, the wrapper script used in the bootstrapped image restores
them to the volumes and performs a much simpler startup sequence.

The base image to use is entirely passed as an ARG, but it will
typically be called by CI, perhaps with a hash-based tag.

ARG heptapod_image
FROM $heptapod_image
COPY bootstrapped-wrapper /assets/
# The wrapper script already takes care of all data initialisation
# we just remove the lines that never return. This is better than
# making our own version that will certainly later diverge from
# upstream GitLab.
# Sometimes `gitlab-ctl stop` can fail, in that case we insist once
# and then proceed, letting the build container termination kill it
# for good. It's been seen for hgitaly only so far. What matters is
# clean termination of postgresql.
