Rails: provide REVISION and HEPTAPOD_REVISION
REVISION
is a part of the Omnibus GitLab that we didn't adapt early on (because we did not yet have a base builder image with Mercurial), but it is expected to be there at the first run of gitlab-ctl reconfigure
.
For the time being, it is created by Heptapod Docker with the same logic as the previously existing HEPTAPOD_REVISION
.
We should take care of both in Omnibus Heptapod, and if possible reduce them to a single one (would involve a small change in Heptapod Rails).
