Comment 6 for bug 1901932

This is finally done. I've force pushed a two-commit branch. Same link. This last commit augments our build process to incorporate the new steps for upgrading the enhanced concerto dataset. It's fairly comprehensive. most of the heavy lifting is done in the perl script. As far as I know, the last place that this needs documenting is our release build wiki page:

https://wiki.evergreen-ils.org/doku.php?id=dev:release_process:evergreen:2.8

Which might want to wait until the branch is merged.
