Description

Azure will sort headers by lowercase value so if there are headers like: B=v1 and a=v2, jclouds will sort them in the order B,a while Azure will sort them as a,B

This will result in an invalid signature.

The failure only appear when copying metadata as the copy options do not lowercase the metadata keys,
