    JCLOUDS-1580 - Add support for lowercase metadata headers
    
    The issue happens if a cloud provider returns lowercase metadata headers, 
for example: "x-object-meta-apiversion" instead of "X-Object-Meta-ApiVersion"
    
    In that case, BlobStore.blobMetadata(CONTAINER, PATH).getUserMetadata()
    incorrectly returns an empty map.
    
    This happens because the code is looking for the exact String "-Meta-" 
(case-sensitive).
    
    This checkin allows to handle metadata headers of any case, and also adds a 
unit test for that situation.
