Description

Current FileSystem APIs include CreateFlag only for the create() api, and some of these (SYNC_BLOCK) are for only client side and will not be stored in metadata of the file. So append() operation will not know about these flags.

It would be Good to support these features for append too.

Compatibility: One more overloaded append API needs to be added to support the flags keeping the current API as is.
