[FEATURE] Introduce scheduler task to execute console commands

This commit introduces a task that is similar to the extbase
task that can run command controllers via the scheduler.

Since TYPO3 8.7 LTS, a lot of command controllers have already
been migrated to symfony console commands, which is breaking
considering the fact that the command controllers could have
been registered as scheduler tasks.

Therefore TYPO3 needs a way to dispatch regular console commands
via the scheduler. This will be achieved by introducing a new
task provided by the scheduler extension which provides a safe
migration path for tx_scheduler records.
