Feature: #79240 - Single cli user for cli commands
See forge#79240
Description
Accessing TYPO3 functionality from the command line has been simplified. Single commands no longer require single
users in the database, instead all cli command use the username _cli_.
This user is created on demand by the framework if it does not exist at the first command line call.
The _cli_ user has admin rights and no longer needs specific access rights assigned to perform specific
tasks like manipulating database content using the Data.
Impact
Creating and managing command line tasks has been simplified, all existing _cli_* users can be deleted.
