Sensible defaults for riak_control

Option 3 as described in basho/platform_tasks#57

• this sets a rational default (no auth implied for Riak Control) and
• when password auth is enabled doesn't create any pre-defined default for user/pass, forcing the admin to do that rather than depend on insecure defaults (see: scott/tiger)

[joedevivo]

For the record, here's the new generated riak.conf section

## Set to 'off' to disable the admin panel.
## 
## Default: off
## 
## Acceptable values:
##   - on or off
riak_control = off

## Authentication mode used for access to the admin panel.
## 
## Default: off
## 
## Acceptable values:
##   - one of: off, userlist
riak_control.auth.mode = off

## If riak control's authentication mode (riak_control.auth.mode)
## is set to 'userlist' then this is the list of usernames and
## passwords for access to the admin panel.
## 
## Acceptable values:
##   - text
## riak_control.auth.user.user.password = pass

👍 to merge, riak_control_authentication passing, code looks good.
