Warn on unknown settings anywhere in the command line	10701	cole-h	Improvements

All nix commands will now properly warn when an unknown option is specified anywhere in the command line.

Before:

$ nix-instantiate --option foobar baz --expr '{}'
warning: unknown setting 'foobar'
$ nix-instantiate '{}' --option foobar baz --expr
$ nix eval --expr '{}' --option foobar baz
{ }

After:

$ nix-instantiate --option foobar baz --expr '{}'
warning: unknown setting 'foobar'
$ nix-instantiate '{}' --option foobar baz --expr
warning: unknown setting 'foobar'
$ nix eval --expr '{}' --option foobar baz
warning: unknown setting 'foobar'
{ }
