feat: Introduce service tier mapping between OpenAI and Bedrock
- Added mapping of OpenAI service tiers (`priority`, `flex`, `default`) to Bedrock service tiers. - Updated request and response handling with new `service_tier` parameter. - Enhanced API documentation and test cases to reflect the changes. - Removed legacy performance configuration and latency mappings.

Protect your applications with content filtering and safety policies using AWS Bedrock Guardrails. This implementation supports the same guardrails integration as AWS Bedrock's native OpenAI-compatible endpoint.
231+
This endpoint supports standard Bedrock headers for enhanced control over your requests. All headers are optional and can be combined as needed.

## Bedrock Service Tier and Performance Configuration
2565+
2566+
Amazon Bedrock service tiers and performance configurations allow you to optimize AI workload performance and cost trade-offs. Configure latency optimization and throughput priority for your inference requests.
2567+
2568+
!!! info "AWS Documentation"
2569+
For detailed information about service tiers, see:
2570+
2571+
- [Amazon Bedrock Service Tiers](https://aws.amazon.com/blogs/aws/new-amazon-bedrock-service-tiers-help-you-match-ai-workload-performance-with-cost/)
2572+
2573+
### Service Tiers
2574+
2575+
Service tiers help you match AI workload performance with cost by selecting the appropriate throughput and latency characteristics:
2576+
2577+
- **`priority`** - Highest priority processing with guaranteed capacity and fastest response times. Best for latency-sensitive applications.
2578+
- **`default`** - Standard processing with balanced performance and cost. Suitable for most production workloads.
2579+
- **`flex`** - Cost-optimized processing with flexible scheduling. Best for batch jobs and non-time-sensitive workloads.
2580+
2581+
### Performance Configuration
2582+
2583+
Performance configuration allows you to optimize for latency:
2584+
2585+
- **`standard`** - Standard latency profile with balanced performance
2586+
- **`optimized`** - Optimized for lowest possible latency
2587+
2588+
### Per-Request Configuration
2589+
2590+
Configure service tier and performance settings per request using HTTP headers. These headers are available on all Bedrock-based routes (Chat Completions, Embeddings, Images):
2591+
2592+
| Header | Purpose | Valid Values |

!!! tip "When to Use Each Tier"
2632+
**Priority Tier:**
2633+
2634+
- Real-time customer-facing applications
2635+
- Interactive chatbots and assistants
2636+
- Applications requiring guaranteed low latency
2637+
- Production workloads with strict SLAs
2638+
2639+
**Default Tier:**
2640+
2641+
- Standard production workloads
2642+
- General-purpose API usage
2643+
- Applications with moderate latency requirements
2644+
2645+
**Flex Tier:**
2646+
2647+
- Batch processing and bulk operations
2648+
- Offline content generation
2649+
- Data processing pipelines
2650+
- Non-time-sensitive workloads
