Centralize CLI registration
Fix to use the correct riak_cli branch

"master" doesn't exist anymore. It has been renamed to "develop".
Rework handoff_status from 55f4518

* Work in progress
* Move away from records toward dicts

  This change lets use keep one data structure for all
  nodes and counts. Dicts offer much nicer merge and map
  semantics than records.

* Implement resize
* Stub out repair outstanding count
Address @ajs style notes and comments
WIP
Fix ups after testing

Works:
* ownership
* hinted handoffs
* resize

TODO:
* repair
Refactored handle_call({repair...}) for readability.
Add a node-level repair_status function
Note unsafe function if node is down
Implement repair outstanding code

Depends on 0259f291
Reformat code with emacs-mode
Some code cleanup preparing to support single-node vs. multi-node results (since we need to support current node, single (other) node, and all nodes).
Updates to handle current/other/all node functionality.
Update summary view to suppress 0 / 0 / 0 cells.
Clean up determine_handoff_target/4 return values
Revert tagged tuples, refactor determine_handoff_target/4 into a series of function headers
Start counting transfers as two values: inbound and outbound
Expose all handoffs from vnode_manager
