Update domain, group, and group_aliases datatypes in the schema for DDF

I tried putting in the operations in the local editor for rule DDF00009. As seen in attached screenshot we need to update schema to accommodate these.

No file, test, or entry point is named. Start by locating the schema definitions used for DDF00009 and compare the current domain, group, and group_aliases datatypes with the attached screenshot; done means the local editor accepts the shown operations and the relevant schema validation passes.
