> Support for customer-provided encryption keys at the file level, superceding 
> the global (account-level) key use in HADOOP-17536.
> ABFS driver will support an "EncryptionContext" plugin for retrieving 
> encryption information, the implementation for which should be provided by 
> the client. The keys/context retrieved will be sent via request headers to 
> the server, which will store the encryption context. Subsequent REST calls to 
> server that access data/user metadata of the file will require fetching the 
> encryption context through a GetFileProperties call and retrieving the key 
> from the custom provider, before sending the request.
