This PR removes environment variable parsing from `/aibridge` directory.
Added env variables/flags for dump dir as coder options.
Only added to new indexed provider options
(`CODER_AIBRIDGE_PROVIDER_<N>_*`) not to deprecated legacy env variables
(`CODER_AIBRIDGE_ANTHROPIC_*` and `CODER_AIBRIDGE_OPENAI_KEY_*`).
Reverted adding `MaxRetries` option as it will be removed soon due to
key failover work:
