Add option to delete user(s)

[atifmir]

Currently, there is no option to delete a user in the administration page. This will improve user's first start experience where they will be able to delete the default admin user; after they have created a new user with admin role.(And the warning message will disappear that warns user to delete default admin user)

This can be a tricky issue... what do we do with the articles they created, their comments, and abide by GDPR?

Whether the user wants to be deleted as part of GDPR or for some other reason, shouldn't the articles and comments "just" be anonymised?

Or the user need to be anonymized isntead. But maybe @WodeCraft's option is cheaper, because it doesn't create "dead users" in the database :-)
