Summary: Incorrect and unclear "vol info" o/p for tiered volume

Version: 3.1

Description of problem:
Incorrect volume info on attaching tier to a disperse volume
Version-Release number of selected component (if applicable):
How reproducible:
Steps to Reproduce:
1. Create a disperse volume
[root at dhcp35-56 ~]# gluster vol create vol2 disperse 6 redundancy 2
10.70.35.56:/rhs/brick1 10.70.35.67:/rhs/brick1 10.70.35.56:/rhs/brick2
10.70.35.67:/rhs/brick2 10.70.35.56:/rhs/brick3 10.70.35.67:/rhs/brick3 force
2.Attach a tier to this volume
[root at dhcp35-56 ~]# gluster vol attach-tier vol2 replica 2
10.70.35.56:/rhs/brick4 10.70.35.67:/rhs/brick4 force
volume add-brick: success
3. Check the volume info
Volume Name: vol2
Type: Tier
Volume ID: b267ba15-82df-4842-bd41-ac233592d5ba
Status: Created
Number of Bricks: 4 x 2 = 8
Transport-type: tcp
Bricks:
Brick1: 10.70.35.67:/rhs/brick4
Brick2: 10.70.35.56:/rhs/brick4
Brick3: 10.70.35.56:/rhs/brick1
Brick4: 10.70.35.67:/rhs/brick1
Brick5: 10.70.35.56:/rhs/brick2
Brick6: 10.70.35.67:/rhs/brick2
Brick7: 10.70.35.56:/rhs/brick3
Brick8: 10.70.35.67:/rhs/brick3
Says "4 x 2 =8", which is incorrect.
Additionally, the volume info should also show the sub components of the tiered
volume. In the above case, the user should be able to figure out that the
volume is a combination of disperse (cold) and replica (hot). Output should
also explicity tell the bricks in either tiers.

I believe this was fixed in a separate bug, assigning to Rafi to see.

This change should not be in "ON_QA", the patch posted for this bug is only
available in the master branch and not in a release yet. Moving back to
MODIFIED until there is an beta release for the next GlusterFS version.
