`ignored_logs` configuration property

The ignored_logs configuration property allows the users on their side to decide which log types should be sent to Understand.io.

An example of config:

    'ignored_logs' => [
        'debug',
        //'info',
        //'notice',
        //'warning',
        //'error',
        //'critical',
        //'alert',
        //'emergency',
    ],

In the example above, debug log type events will not be sent to Understand.io.

You have to publish the config file to be able to make these changes. See https://github.com/understand/understand-laravel5#advanced-configuration
