Description

Currently Azure WASB adapter code supports wasb url in this format wasb://[containername@]youraccount.blob.core.windows.net/testDir with the credentials retrieved from configuration and scoped to a container.
With this change we want
1) change the url to contain file level sas token in the url
wasb://[containername[:<Base64UrlEncodedFileSAStoken>]]@youraccount.blob.core.windows.net/testDir
2) Scope access to a blob/file level.
3) Tests to test the new url format
