Description

Currently in azure FS, setOwner api is exposed to all the users accessing the file system.
When Authorization is enabled, access to some files/folders is given to particular users based on whether the user is the owner of the file.
So setOwner has to be restricted to limited set of users to prevent users from exploiting owner based authorization of files and folders.

Introducing a new config called fs.azure.chown.allowed.userlist which is a comma seperated list of users who are allowed to perform chown operation when authorization is enabled.
