When running `do cairn-createuser`, the created db did not have the
right name. If the user had been created earlier with SSO, then the
Clickhouse DB did not exist.
This upgrade includes SSO login. Finally! We can now login to Superset
via the LMS. Thanks to OARS for providing the base security manager
implementation!
Here, we make it possible to add a "-nightly" suffix to the package
version. This suffix will find its way to the Docker image tags. Thus,
the nightly branch will have different image tags. This will resolve
some confusion, as image tags are currently identical in nightly and
master.
CI was failing during `apt update` with the following error:
E: The repository 'https://repo.clickhouse.com/deb/stable main/ Release' does not have a Release file.
Note that this error was occurring in the UK and Germany, but not in
France.
Clickhouse client command was triggering a permission denied error:
$ tutor local run cairn-clickhouse cairn-client
Code: 586. DB::ErrnoException: Cannot create file:
//.clickhouse-client-history, errno: 13, strerror: Permission denied.

This was because the home of the cairn client was set to "/".
"Course completion" was causing browser crashes when it attempted to display
10k course items (which is the maximum allowed). Displaying 10000 bars does not
make sense anyway, so we threshold this number to 100.
Superset was ignoring the cairn-redis container, so we decided to remove it.
But the superset celery worker was writing to the /0 database, which conflicts
with the default celery database from the lms/cms. We fix this issue by running
in a different database.
The CELERY_RESULT_BACKEND seemed to be completely useless, so we got rid of it.
Vector is spamming us with messages concerning absent containers. Such messages include:

This issue has affected multiple users in the past. To address it, we first
tried to upgrade Vector, which did not help. Thus, we decided to reduce the
verbosity of Vector.
When creating a new user, but with an email address already associated
to a different user, the `cairn createuser` script crashes with an
obscure error. This slightly improves the error messsage.

This is necessary for some customers who are not using the
common.djangoapps.track.shim.LegacyFieldMappingProcessor in
settings.EVENT_TRACKING_BACKENDS.
