Bumping the `OPENEDX_COMMON_VERSION` in the master branch usually
creates a conflict when we merge the change in the nightly branch. To
avoid this conflict, we add some logic to the `OPENEDX_COMMON_VERSION`.
This change should be invisible for most users.
This partially addresses issue #936.
MySQL 8 defaults to a binlog expiry period of 2592000 seconds
(30 days), which for Tutor/Open edX purposes can be considered
excessive.
On the one hand, it is unlikely that a MySQL server configured for
Tutor uses MySQL replication at all (considering that up until Tutor
15 and MySQL 5.7, the binlog was disabled by default, rendering
replication impossible). Even if it does, a replica lagging more than
two days behind the primary server would be unacceptable.
Likewise, it is unlikely that an Open edX database is backed up less
than once a day, thus is is unlikely that Open edX admins would
benefit from the ability to do point-in-time restore over a 30-day
period.
On the other hand, having a 30-day binlog expiry period can
considerably increase the storage space requirements for the MySQL
container, particularly on busy Open edX platforms. When left
unchecked, this can even cause the MySQL container to run into "No
space left on device" situations, disabling the MySQL database
altogether. Thus, the MySQL default settings are likely to be a net
disadvantage for Open edX admins.
Finally, all of the above considerations apply only if the Open edX
administrator has chosen to run their own MySQL and not opted for a
DBaaS solution like AWS RDS.
Thus, it should be acceptable to run with a reduced binlog expiry
period of 3 days (rather than 30) by default.
Therefore, inject the --binlog-expire-logs-seconds=259200 argument
into the Tutor-generated command to start mysqld.

On macOS, building the "openedx-dev" Docker image resulted in an image that required more than 600 GB of disk space. This was due to the `adduser` command which was called with a user ID of 2x10⁹ (on macOS only). This resulted in a very large /var/log/faillog file, hence the image size.

On Oct. 10, py2neo package was abruptly removed from pypi, GitHub, and
the py2neo website now displays just a super funny meme: https://py2neo.org/
Yes, we should get rid of that dependency, but we are still supposed to
support existing users. So we install py2neo from our fork.
The LMS was overriding CMS_BASE properly, but Studio (CMS) configuration
was not. That meant that Studio's CMS_BASE in dev mode was using the
devstack default of localhost:18010 (because this is what's defined in
edx-platform). This in turn broke parts of Studio that use this value,
such as the XBlock v2 API (/api/xblock/v2).
This commit derives the value of the CMS_BASE Django setting from
Tutor's CMS_HOST config value, in the same way that the LMS does it.
