add db_upgrade test
We have a database schema upgrade path, but so far nothing that verifies that
we don't break it. It almost seems like the user data weren't important to us!?
Add a db upgrade test:
- Create a db with an .sql dump taken from a db created with an old osmo-hlr,
producing DB schema version 0.
- Run osmo-hlr --db-upgrade --db-check
- Verify that the upgrade exited successfully.
- Verify that restarting with the upgraded DB works.
If python tests are enabled, also:
- create a new database using the new osmo-hlr (just built).
- replay a VTY transcript to create subscribers as in the old snapshot.
- replay some sql modifications as done in the old snapshot.
- Get a list of sorted table names,
- a list of their sorted columns with all their properties,
- and dump the table contents in a column- and value-sorted way.
- Compare the resulting dumps and error if there are any diffs.
(This is how I found the difference in the imei column that was fixed in
