Retrying internal errors in files_upload_v2

Hi there,

We occasionally see transient errors from the Slack API in calls to files.completeUploadExternal that are done within the SDK's implementation of files_upload_v2. The error we see most frequently error we encounter is file_update_failed, which has more or less no useful explanation on the API docs. Support has also not been very helpful in understanding the nature of these issues: they just said there is a temporary server error, and we should retry the call to completeUploadExternal

Can the Python SDK implement that retr? It doesn't seem like the caller of files_upload_v2 (i.e. our code) could, since that would redo the entire upload. The caller also doesn't have enough information to retry the files.completeUploadExternal call, since the ID is lost when the SDK throws an exception.

I suppose a workaround is to install a custom RetryHandler on the WebClient. But like in #1715, shouldn't that just be part of the SDK?

Python SDK の WebClient.files_upload_v2 の実装から開始し、その files.completeUploadExternal 呼び出しを追跡します。file_update_failed などの一時的な内部エラーについて、アップロードを繰り返さずに再試行する方法を特定し、その後、既存の WebClient エントリポイントを通じて完了したアップロードが引き続き成功することを確認します。
