In the parent task, we're going to change the defaults for whom UserInfoCard is turned on by default. However, for those people who will no longer have UIC turned on by default, we'd like to preserve it by switching a global preference for them. Given that currently there is no maintenance script for that, we'd like to implement one.
Acceptance criteria
- There exists a maintenance script in GlobalPreferences, which can be used to set a preference to a given value for an arbitrary list of user names (loaded from file)
