+    tier: separation of attach-tier from add-brick
+    
+    PROBLEM: Both attach tier and add brick have the same RPC
+    and set of code. This becomes a hurdle while tring to implement
+    add brick on a tiered volume.
+    
+    FIX: This patch separates the add brick and attach tier
+    giving them separate RPCs.
