Added custom logic to check if a request/response should be logged

You can now add your own custom logic to specify if a request/response should be logged. Comes with 3 new adapters out of the box:

• LogAll - log request & response
• LogClientErrorsOnly - log only responses that have an http status code of 4XX
• LogSuccessOnly - log only responses that have an http status code of 2XX

Upgrade from 1.0.X -> 2.0.X

1. Install v2.0.X with composer
2. Add the following to the bottom of your config/log-requests-and-responses.php:

/**
 * The class responsible for determining if a request should be logged.
 * 
 * Out of the box options are:
 * Mtownsend\RequestResponseLogger\Support\Logging\LogAll::class,
 * Mtownsend\RequestResponseLogger\Support\Logging\LogClientErrorsOnly::class,
 * Mtownsend\RequestResponseLogger\Support\Logging\LogSuccessOnly::class,
 */
'should_log_handler' => \Mtownsend\RequestResponseLogger\Support\Logging\LogAll::class,
