Allow for placement of files on storage devices selectively for best performance.
For example, regularly accessed or newer files should be placed on faster disks, while less relevant data is placed on slower disks. BZ 826758
Display sync status of selected geo-replication relationships, including dynamically updated file counts and byte counts replicated on this pass and remaining to replicate.
Add a "preview" option for gluster volume rebalance which shows a user how many files and MB of data have to be rebalanced (either due to add-brick operation or due to changes in the file names).
