posix: APIs in posix to get and set time attributes
This is part of the effort to provide consistent time across distribute and replica set for time attributes (ctime, atime, mtime) of the object. This patch contains the APIs to set and get the attributes from on disk and in inode context. Credits: Rafi KC <rkavunga@redhat.com> Updates: #208 Change-Id: I5d3cba53eef90ac252cb8299c0da42ebab3bde9f Signed-off-by: Kotresh HR <khiremat@redhat.com>
