atkgen - add configurability, allow config of which adversarial gener…

…ator to use (#777)

* make non-descriptive attribs configurable

* var rename

* permit streamlined config of atkgen red team model

* expose more atkgen behavior config in default params

* don't require a prompt template, if we're not using one

* finally some atkgen test

* test atkgen custom generator loading

* prune comments

* appease linter
