added support for extra cuttlefish commands

[joedevivo]

Added support for

• $runner config effective
• $runner config describe VARIABLE

[jaredmorrow]

Calling riak config does not print out any help describing the possible commands.

[jaredmorrow]

The riak config describe command should catch the arg count at the shell level to prevent leaking cuttlefish output through to the shell.

./bin/riak config describe 
cuttlefish's describe command required a variable to query.
Try `describe setting.name`

Users would most likely think, "what does a cuttlefish have to do with anything?"

[joedevivo]

That's actually hardcoded io:format in cuttlefish's escript. I can change the wording over there to be "The describe command...", but that shouldn't hold up this review.

[jaredmorrow]

No, what I'm saying is you can catch the fact that there are not enough params given to 'config describe' and print help. That will tie into not enough params to 'config'

[joedevivo]

Ooooh. I get it.

[jaredmorrow]

https://github.com/basho/riak/blob/develop/rel/files/riak-admin#L199 bucket-type or security subcommands are good examples.

[jaredmorrow]

Nothing big, just minor user friendliness fixes.

[joedevivo]

Yeah, that's the whole point of the cuttlefish stuff, so I'm all for this kind of attention
