Fail on unknown variable

[joedevivo]

Currently, cuttlefish prints a warning about unknown configuration variables but continues on using the default.

If I were trying to set anti_entropy = passive and accidentally typed anti_entrophy, riak would start with the default of active. You could check the logs and see the warning, but if you just run riak start, there's no information on the console.

app.config would have worked the same way, so it's not crazy behavior, but cuttlefish is better than that.

Also related is a possible issue with node_package. It should be displaying this warning message when you run riak start I think both need to be addressed.

displaying this message during riak start is too much work for such little reward. The following user experience is fine:

➜  riak git:(develop) ✗ ./bin/riak start  
riak failed to start within 15 seconds,
see the output of 'riak console' for more information.
If you want to wait longer, set the environment variable
WAIT_FOR_ERLANG to the number of seconds to wait.
➜  riak git:(develop) ✗ ./bin/riak console
