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.

+// Completes a multipart upload by assembling previously uploaded parts. You first
+// initiate the multipart upload and then upload all parts using the UploadPart (https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html)
+// operation. After successfully uploading all relevant parts of an upload, you
+// call this action to complete the upload. Upon receiving this request, Amazon S3
+// concatenates all the parts in ascending order by part number to create a new
+// object. In the Complete Multipart Upload request, you must provide the parts
+// list. You must ensure that the parts list is complete. This action concatenates
+// the parts that you provide in the list. For each part in the list, you must
+// provide the part number and the ETag value, returned after that part was
+// uploaded. Processing of a Complete Multipart Upload request could take several
+// minutes to complete. After Amazon S3 begins processing the request, it sends an
+// HTTP response header that specifies a 200 OK response. While processing is in
+// progress, Amazon S3 periodically sends white space characters to keep the
+// connection from timing out. A request could fail after the initial 200 OK
+// response has been sent. This means that a 200 OK response can contain either a
+// success or an error. If you call the S3 API directly, make sure to design your
+// application to parse the contents of the response and handle it appropriately.
+// If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect
+// the embedded error and apply error handling per your configuration settings
+// (including automatically retrying the request as appropriate). If the condition
+// persists, the SDKs throws an exception (or, for the SDKs that don't use
+// exceptions, they return the error). Note that if CompleteMultipartUpload fails,
+// applications should be prepared to retry the failed requests. For more
+// information, see Amazon S3 Error Best Practices (https://docs.aws.amazon.com/AmazonS3/latest/dev/ErrorBestPractices.html)
+// . You cannot use Content-Type: application/x-www-form-urlencoded with Complete
+// Multipart Upload requests. Also, if you do not provide a Content-Type header,
+// CompleteMultipartUpload returns a 200 OK response. For more information about
+// multipart uploads, see Uploading Objects Using Multipart Upload (https://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.html)
+// . For information about permissions required to use the multipart upload API,
+// see Multipart Upload and Permissions (https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuAndPermissions.html)
+// . CompleteMultipartUpload has the following special errors:
+//   - Error code: EntityTooSmall
+//   - Description: Your proposed upload is smaller than the minimum allowed
+//     object size. Each part must be at least 5 MB in size, except the last part.
+//   - 400 Bad Request
+//   - Error code: InvalidPart
+//   - Description: One or more of the specified parts could not be found. The
+//     part might not have been uploaded, or the specified entity tag might not have
+//     matched the part's entity tag.
+//   - 400 Bad Request
+//   - Error code: InvalidPartOrder
+//   - Description: The list of parts was not in ascending order. The parts list
+//     must be specified in order by part number.
+//   - 400 Bad Request
+//   - Error code: NoSuchUpload
+//   - Description: The specified multipart upload does not exist. The upload ID
+//     might be invalid, or the multipart upload might have been aborted or completed.
