Create a cli script to allow for bulk delete of users from commandline
The script should be able to:
 - delete all users that have never logged in (created by admin)
 - and/or delete all users that have not logged in since a certain date
 - and/or delete only those users from a certain institution To allow a server admin to clean up a site

Bug 1760767: Create a cli script to allow for bulk delete of users from commandline

To allow a server admin to clean up a site

The script should be able to:
- delete all users that have never logged in (created by admin)
- and/or delete all users that have not logged in since a certain date
- and/or delete only those users from a certain institution

The script has a 'dryrun' flag set to false by default to allow one to
check how many users will be deleted before actually doing the deletion

TODO
- do more checks
