YQ Connector: prepare code base for S3 integration

1. Кодовая база Коннектора переписана с помощью Go дженериков так, чтобы добавление нового источника данных (в частности S3 + csv) максимально переиспользовало имеющийся код (чтобы сохранялась логика нарезания на блоки данных, учёт трафика и пр.)
2. API Connector расширено для работы с S3, но ещё пока не протестировано.

+// Enables notifications of specified events for a bucket. For more information
+// about event notifications, see Configuring Event Notifications (https://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html)
+// . Using this API, you can replace an existing notification configuration. The
+// configuration is an XML file that defines the event types that you want Amazon
+// S3 to publish and the destination where you want Amazon S3 to publish an event
+// notification when it detects an event of the specified type. By default, your
+// bucket has no event notifications configured. That is, the notification
+// configuration will be an empty NotificationConfiguration .  This action
+// replaces the existing notification configuration with the configuration you
+// include in the request body. After Amazon S3 receives this request, it first
+// verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon
+// Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner
+// has permission to publish to it by sending a test notification. In the case of
+// Lambda destinations, Amazon S3 verifies that the Lambda function permissions
+// grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For
+// more information, see Configuring Notifications for Amazon S3 Events (https://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html)
+// . You can disable notifications by adding the empty NotificationConfiguration
+// element. For more information about the number of event notification
+// configurations that you can create per bucket, see Amazon S3 service quotas (https://docs.aws.amazon.com/general/latest/gr/s3.html#limits_s3)
+// in Amazon Web Services General Reference. By default, only the bucket owner can
+// configure notifications on a bucket. However, bucket owners can use a bucket
+// policy to grant permission to other users to set this configuration with the
+// required s3:PutBucketNotification permission. The PUT notification is an atomic
+// operation. For example, suppose your notification configuration includes SNS
+// topic, SQS queue, and Lambda function configurations. When you send a PUT
+// request with this configuration, Amazon S3 sends test messages to your SNS
+// topic. If the message fails, the entire PUT action will fail, and Amazon S3 will
+// not add the configuration to your bucket. If the configuration in the request
+// body includes only one TopicConfiguration specifying only the
+// s3:ReducedRedundancyLostObject event type, the response will also include the
+// x-amz-sns-test-message-id header containing the message ID of the test
+// notification sent to the topic. The following action is related to
