> This is a feature proposed by [~ben-zvi].
> Currently all the options are accessible by the user in sys.options. We would
> like to add internal options which can be altered, but are not visible in the
> sys.options table. These internal options could be seen by another alias
> select * from internal.options. The intention would be to put new options we
> weren't comfortable with exposing to the end user in this table.
> After the options and their corresponding features are considered stable they
> could be changed to appear in the sys.option table.
> A bunch of other fixes to the Option system have been clubbed into this:
> * OptionValidators no longer hold default values. Default values are
> contained in the SystemOptionManager
> * Options have an OptionDefinition. The option definition includes:
> * A validator
> * Metadata about the options visibility, required permissions, and the
> scope in which it can be set.
> * The Option Manager interface has been cleaned up so that a Type is not
> required to be passed in in order to set and delete options
