[v1.8.x] Add restart command

[gajosu]

This is a proposal to have the possibility to restart consumer processes by means of an Artisan command

Changes

• New comand kafka:restart-consumers
  When this command is executed, a key cache called laravel-kafka:consumer:restart is created with the current date in timestamp format, the kafka process checks the cache every 1 second (you can define the interval in milliseconds in the Config class), when the timestamp is different from the last restart the loop stops.

Feel free to send your suggestions

Hey @gajosu didn't have time to review this one. You can reopen if you want, I'll review all pending PRs on my open source projects tomorrow. Thanks!

Hey @gajosu I've just tested it here, and when I have my consumer running as a Laravel Command, I call kafka:restart and the command just stops. Since the command is called restart, isn't it supposed to start again? I think the only way the consumer will start again is if it's running via supervisor, and that's fine for me, I just want to confirm with you first.

[gajosu]

yes the loop just stops, just like laravel queues, the queue:restart command stops the loop and supervisor needs to restart it

Ok, thanks.
