content_type needs to be renamed as it has been added as reserved word in Aurora MySQL version 3.06.0
As far as I can tell content_type doesn't appear to be used outside of backup/restore - but I've kept it in case I've missed something or it was used historically.
One note is that when using Aurora MySQL version 3.06.0 or above, this requires 'content_type' to be added to the mysql reserved words list as per https://tracker.moodle.org/browse/MDL-81751
Closes #549
