These changes make to possible to run:
tutor mounts add /path/to/my-xblock
The xblock directory with then be auto-magically bind-mounted in the
"openedx" image at build time, and the lms*/cms* containers at run time.
This makes it effectively possible to work as a developer on
edx-platform requirements.
We take the opportunity to move some openedx-specific code to a
dedicated module.

The new domain name points to 127.0.0.1, just like the previous one. We
keep the local.overhang.io domain names for backward compatibility. In
the future, we hope to migrate to "*.openedx.io" but that will not
happen before Redwood.
Close #945
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.
