Follow-up of story #8528

The purpose of this story is to desactivate accounts that were created "just for import"

• At import, accounts are created with a reference to a DB table
  • Table format:
    • import date
    • who run the import
    • previous status (if any)
    • when the account was "restored" (this is useful to detect pending users if process abort with fatal error or segfault, etc)
  • If accounts already exists but not with an active status, they are temporarly activated (keep track in table) but password is "unactivated" (for instance add !! in front of hash)
• After the import is completed or in case of catchable error (Exception)
  • Accounts that were created are turned off (Deleted)
  • Accounts that were temporarly activated are reset to their original state
    • Password is restored
  • Remove temporary option --force-create-all-users-active
• There is a dedicated tool that can be run to identify if there are user accounts that should have been desactivated but that are not (to be run in case of crash for instance)
