(core) add a checkbox for owner "boss mode"

Summary:
Implement a checkbox that grants owners full access to tables by default, when creating new table/column rules.
 * Checkbox appears above default rules.
 * When set, a rule giving owners full access will be inserted in any new rule set started for tables or columns.
 * The checkbox can be expanded to allow customization of the rules.
