There's no need for an extra blobExists() call when writing a blob to the Azure service. Azure provides an option (with stronger consistency guarantees) on the upload method that guarantees that the blob that's uploaded does not already exist. This saves one network roundtrip.

I have not tested this against the real Azure service, only used the API docs to develop this. @tlrx can you help me check that this works against the actual Azure service? Thanks.

Relates to #19749

LGTM

I tested this change both manually and with the QA tests.

if (se.getHttpStatusCode() == HttpURLConnection.HTTP_CONFLICT) {
throw new FileAlreadyExistsException(blobName, null, se.getMessage());

Sorry, I saw that after the LGTM: we should rethrow the exception, right?
