Retrying Commerce Integration Creation on Falure.

[message-dimke]

Changes proposed in this Pull Request:

This PR introduces the initial create Commerce Integration call retry procedure. It may happen that the Create Integration API will fail. We have to retry its creation since the integration data is crucial for assigning customers to a proper Pinterest advertisement platform on the Pinterest side.

The code will try three times: in a minute after the initial failure; in an hour; in a day.

Detailed test instructions:

1. Add a filter to make the APIV5::create_commerce_integration call fail.

add_filter(
	'pre_http_request',
	function ( $response, $parsed_args, $url ) {
		if (
			'https://api.pinterest.com/v5/integrations/commerce' === $url &&
			'POST' === $parsed_args['method']
		) {
			return array(
				'headers' => array(
					'content-type' => 'application/json',
				),
				'body' => json_encode(
					array(
						'code'    => 911,
						'message' => 'Oops! Something went wrong!',
					)
				),
				'response' => array(
					'code'    => 500,
					'message' => 'Unexpected error',
				),
				'cookies'  => array(),
				'filename' => '',
			);
		}

		return $response;
	},
	10,
	3
);

Lines 407 to 413 in f48b082

	public static function create_commerce_integration( array $integration_data ): array {
	return self::make_request(
	'integrations/commerce',
	'POST',
	$integration_data
	);
	}

2. If you are connected to Pinterest - disconnect. Otherwise, connect to your Pinterest account using the extension.
3. During the connection procedure, the commerce integration call will fail. Look into Pending Scheduled Actions for a retry scheduled to run within a minute of the connection time.

It should also have an attempt number parameter set to 1, meaning this is the first attempt of a retry.

4. Look into pinterest-for-woocommerce log for a message about the failure and the retry procedure.

5. Wait until the action triggers itself or force-run it. Since we still have a code to make the endpoint fail, we should see another retry attempt scheduled and the log message.

6. Do not wait an hour 🤡 to pass and force-run the action.
7. Look for the last, third attempt to get scheduled.

8. Force-run it and check no more actions scheduled and the last attempt log message written.
