add console commands to list [hits, notified], event BotBlockedEvent

[AMoktar]

php artisan block-bots:list-hits
php artisan block-bots:list-notified

I had to modify the key attribute

laravel-block-bots/src/Contracts/Client.php

Line 29 in 43f552d

$this->key = "block_bot:{$this->id}";

and adding prefix

$this->key = "block_bot:hits:{$this->id}"

so I can use this prefix in commands like so

$keys = Redis::keys('block_bot:hits*');

Also I've added an event BotBlockedEvent
