luci-app-unbound: add statistics and manual edit tabs

Add an option to "Basic Settings" tab to expand LuCI. This option
will add tab hierarchy for the settings, statistics, and raw view
or editing of configuration files. If you have unbound-control
installed, then you can see some useful debug information.
