Remove config singleton

[waynehamadi]

Background

There were a few more calls to config() in the codebase.

Changes

• removed remaining calls to config()
• removed config being a singleton. This means it's not allowed to call it initialize it twice in the autogpt folder. (we still initialize it once in pytest.
• removed flaky because it's slowing down the pipeline: a flaky challenge should be discarded from the pipeline anyway, there is no point keeping it.
• the service unavailable 503 error is a new error OpenAI has been giving recently, we want to retry that so it's been added to the retry_api decorator.
