Thanks for the PR! Just a couple remarks:

• We try to follow the same api as the .net client.

https://learn.microsoft.com/en-us/dotnet/api/azure.storage.blobs.models.blobhttpheaders?view=azure-dotnet

• This means moving the http headers into a separate class BlobHttpHeaders that we can reuse everywhere.

• Please also add it to all the different upload methods. (single, sequential and parallel)
