[BETA] Add OpenAI /images/variations + Topaz API support (#7700)

Browse source 
* feat(main.py): initial commit for `/image/variations` endpoint support

* refactor(base_llm/): introduce new base llm base config for image variation endpoints

* refactor(openai/image_variations/transformation.py): implement openai image variation transformation handler

* fix: test

* feat(openai/): working openai `/image/variation` endpoint calls via sdk

* feat(topaz/): topaz sync image variation call support

Addresses https://github.com/BerriAI/litellm/issues/7593

'

* fix(topaz/transformation.py): fix linting errors

* fix(openai/image_variations/handler.py): fix passing json data

* fix(main.py): image_variation/

support async image variation route - `aimage_variation`

* fix(test_get_model_info.py): fix test

* fix: cleanup unused imports

* feat(openai/): add async `/image/variations` endpoint support

* feat(topaz/): support async `/image/variations` calls

* fix: test

* fix(utils.py): fix get_model_info_helper for no model info w/ provider config

handles situation where model info is not known but provider config exists

* test(test_router_fallbacks.py): mark flaky test

* fix: fix unused imports

* test: bump otel load test perf threshold - accounts for current load tests hitting same server
