### Commit Message
#### Refactor Prometheus Validation Mode
- **Replace `is_strict_mode` with `PromValidationMode` Enum:**
- Updated `HttpOptions` and related structures to use `PromValidationMode` enum instead of the boolean `is_strict_mode`.
- Modified functions and tests to accommodate the new enum, ensuring flexible validation modes (`Strict`, `Lossy`, `Unchecked`).
- Affected files: `server.rs`, `prom_decode.rs`, `http.rs`, `prom_store.rs`, `prom_row_builder.rs`, `proto.rs`, `prom_store_test.rs`, `test_util.rs`, `http.rs`.
- **Enhance UTF-8 String Decoding:**
- Introduced `decode_string` function to handle UTF-8 string decoding based on the selected `PromValidationMode`.
- Affected files: `proto.rs`, `prom_row_builder.rs`.
This refactor improves the flexibility and clarity of Prometheus request handling by allowing different validation strategies.
* feat/lossy-string-validation-in-prom-remote-write:
- **Add Prometheus Validation Mode Configuration:**
- Updated `config/config.md`, `config/frontend.example.toml`, and `config/standalone.example.toml` to include `http.prom_validation_mode` setting for Prometheus remote write requests.
- **Enhance Benchmarking for Prometheus Requests:**
- Modified `src/servers/benches/prom_decode.rs` to benchmark different Prometheus validation modes (`Strict`, `Lossy`, `Unchecked`).
- **Implement and Test String Decoding:**
- Added `decode_string` function and comprehensive tests in `src/servers/src/proto.rs` to handle string decoding with different validation modes.

### Add Histogram Buckets to Metrics
- **Files Modified**: `src/servers/src/metrics.rs`
- **Key Changes**:
- Added specific histogram buckets to `METRIC_MYSQL_QUERY_TIMER`, `METRIC_POSTGRES_QUERY_TIMER`, and `METRIC_SERVER_GRPC_PROM_REQUEST_TIMER` to enhance granularity in query elapsed time metrics.

### Update Prometheus Validation Mode Default
- **Config Documentation**: Updated the default description for `http.prom_validation_mode` to indicate that "strict" is the default option in `config.md`, `frontend.example.toml`, and `standalone.example.toml`.
- **HTTP Server Implementation**: Changed the default `prom_validation_mode` to `PromValidationMode::Strict` in `src/servers/src/http.rs`.

**Commit Message:**
Update Prometheus Validation Mode to Strict
- Changed `http.prom_validation_mode` from `unchecked` to `strict` in `config.md`, `frontend.example.toml`, and
`standalone.example.toml` to enforce strict validation of Prometheus remote write requests.
