WIP console callbacks for TicTac AAE CLI commands

[hmmr]

This PR implements "Tictac runtime management and reporting" section of the TicTac AAE and NextGenRepl CLI commands proposal.

The riak_kv_console:titacaae_cmd/1 functions will be exposed as the following riak admin commands:

Tictac AAE runtime management and reporting

  riak admin tictacaae rebuild_schedule [-n NODE] [-p PARTITION] [RW RD]
  riak admin tictacaae storeheads [-n NODE] [-p PARTITION] [VALUE]
  riak admin tictacaae tokenbucket [-n NODE] [-p PARTITION] [VALUE]
  riak admin tictacaae rebuildtick|exchangetick|maxresults|rangeboost [-n NODE] [VAL]
  riak admin tictacaae rebuild-soon [-n NODE] [-p PARTITION] DELAY
  riak admin tictacaae rebuild-now [-n NODE] [-p PARTITION] DELAY
  riak admin tictacaae rebuildtreeworkers|rebuildstoreworkers|aaefoldworkers [-n NODE] POOLSIZE
  riak admin tictacaae treestatus [--format table|json] [--show STATES]

Notes:

• Commands rebuildtick, exchangetick, maxresults, rangeboost are simple set/show commands, reading and setting the corresponding app env vars in the riak_kv app, on local node by default or on other node if specified with option -n.

• rebuild-soon will schedule a tree rebuild, and rebuild-now will additionally send a poke to controller(s) associated with partitions or nodes as specified with options -n and -p.

• Commands storeheads, tokenbucket, rebuild_schedule will extract or inject the actual relevant values from/to the state of the running AAE controller processes.

• Commands rebuildtreeworkers, rebuildstoreworkers, aaefoldworkers will read/set the size of worker pools af1, af4 and be, correspondingly.

• The treestatus command will collect various items from running AAE contollers and produce a report like this:

$ ./dev/dev1/riak/bin/riak admin tictacaae treestatus --show=all
                                        Partition ID      Status      Last Rebuild Date     Next Rebuild Date   Controller PID  Key Store Status

AAE fold operations

  riak tictacaae fold list-buckets NVAL
  riak tictacaae fold find-keys BUCKET KEY_RANGE MODIFIED_RANGE sibling_count=COUNT|object_size=BYTES
  riak tictacaae fold find-keys BUCKET KEY_RANGE MODIFIED_RANGE sibling_count=COUNT|object_size=BYTES
  riak tictacaae fold find|count-tombstones KEY_RANGE SEGMENTS MODIFIED_RANGE
  riak tictacaae fold reap-tombstones KEY_RANGE SEGMENTS MODIFIED_RANGE CHANGE_METHOD
  riak tictacaae fold object-stats BUCKET KEY_RANGE MODIFIED_RANGE
  riak tictacaae fold erase-keys BUCKET KEY_RANGE SEGMENTS MODIFIED_RANGE CHANGE_METHOD
  riak tictacaae fold repair-keys BUCKET KEY_RANGE MODIFIED_RANGE

These will call the corresponding aae_fold operation and dump results in JSON format in a file named "aaefold-%o-results-%t.json", where "%o" will be substituted with the operation being performed, and "%t", with the current datetime string, or to a file explicitly specified with option -o.

Depends on these PRs: OpenRiak/kv_index_tictactree#4, OpenRiak/riak_core#20 and OpenRiak/poolboy#1.

Required by OpenRiak/riak#13.

Integration tests in https://github.com/OpenRiak/riak_test/pull/38.

After converting it to use clique, this PR is great again and ready for review.

Note that OpenRiak/poolboy#1 and OpenRiak/kv_index_tictactree#4 as well as OpenRiak/riak_core#20 need to be dealt with first.
