Add auth to StartWorkerCommand

PHP8only branch, Add auth to StartWorkerCommand. Thanks @mrardon for #61

Cleanup Commands and use Attributes

Resolves Symfony compatibility moaning about use of $name in constructors - so moved to PHP8 attributes for name/description of commands

PHP 7 fixes to allow job failure with Exception or Error throwables

Fully backward compatible changes.

New Series: PHP 8+ and Symfony 5.3.1+ only !

The 5.x series of this bundle is targeted at PHP 8 and Symfony 5.3 and should not be used on anything less than that.

Return correct exit codes in commands

This release is the backward compatible release, and correctly returns command exit codes for compatibility with Symfony 5.3
