Download from Azure Blob storage times out in 60 seconds

[mxalis]

When downloading backups from Azure Blob storage, the default go library uses a 60 seconds timeout. This will cause downloads to fail (and therefore backup restore) if either your connection is slow or the file is large.

Can be fixed by adding the TryTimeout option to https://github.com/AlexAkulov/clickhouse-backup/blob/820961e12158a39772b370dd8460f408c4833f70/pkg/new_storage/azblob.go#L99

eg. increasing it to 15 minutes

s.Container = azblob.NewServiceURL(*u, azblob.NewPipeline(credential, azblob.PipelineOptions{
                                Retry: azblob.RetryOptions{
			                    TryTimeout: 15 * time.Minute,
			                    },
		                  })).NewContainerURL(s.Config.Container)

It would be great to have the timeout configurable with a reasonable default (eg 5 mins). Unfortunately I am a golang noob and cannot help you with a pull request

Faced same problem.
@Slach is it possible to apply fix for v1 version?
