### Enhance Pipeline Processing for One-to-Many Transformations
- **Support One-to-Many Transformations**:
- Updated `processor.rs`, `etl.rs`, `vrl_processor.rs`, and `greptime.rs` to handle one-to-many transformations by allowing VRL processors to return arrays, expanding each element into separate rows.
- Introduced `transform_array_elements` and `values_to_rows` functions to facilitate this transformation.
- **Error Handling Enhancements**:
- Added new error types in `error.rs` to handle cases where array elements are not objects and for transformation failures.
- **Testing Enhancements**:
- Added tests in `pipeline.rs` to verify one-to-many transformations, single object processing, and error handling for non-object array elements.
- **Context Management**:
- Modified `ctx_req.rs` to clone `ContextOpt` when adding rows, ensuring correct context management during transformations.
- **Server Pipeline Adjustments**:
- Updated `pipeline.rs` in `servers` to handle transformed outputs with one-to-many row expansions, ensuring correct row padding and request formation.

### Enhance Pipeline Transformation with Per-Row Table Suffixes
- **`src/pipeline/src/etl.rs`**: Updated `TransformedOutput` to include per-row table suffixes, allowing for more flexible routing of transformed data. Modified `PipelineExecOutput` and related methods to
handle the new structure.
- **`src/pipeline/src/etl/transform/transformer/greptime.rs`**: Enhanced `values_to_rows` to support per-row table suffix extraction and application.
- **`src/pipeline/tests/common.rs`** and **`src/pipeline/tests/pipeline.rs`**: Adjusted tests to validate the new per-row table suffix functionality, ensuring backward compatibility and correct behavior in
one-to-many transformations.
- **`src/servers/src/pipeline.rs`**: Modified `run_custom_pipeline` to process transformed outputs with per-row table suffixes, grouping rows by `(opt, table_name)` for insertion.

### Update VRL Processor Type Checks
- **File:** `vrl_processor.rs`
- **Changes:** Updated type checking logic to use `contains_object()` and `contains_array()` methods instead of `is_object()` and `is_array()`. This change ensures
compatibility with VRL type inference that may return multiple possible types.

- **Enhance Error Handling**: Added new error types `ArrayElementMustBeObjectSnafu` and `TransformArrayElementSnafu` to improve error handling in `etl.rs` and `greptime.rs`.
- **Refactor Error Usage**: Moved error usage declarations in `transform_array_elements` and `values_to_rows` functions to the top of the file for better organization in `etl.rs` and `greptime.rs`.

### Update `greptime.rs` to Enhance Error Handling
- **Error Handling**: Modified the `values_to_rows` function to handle invalid array elements based on the `skip_error` parameter. If `skip_error` is true, invalid elements are skipped; otherwise, an error is returned.
- **Testing**: Added unit tests in `greptime.rs` to verify the behavior of `values_to_rows` with different `skip_error` settings, ensuring correct processing of valid objects and appropriate error handling for invalid elements.

### Commit Summary
- **Enhance `TransformedOutput` Structure**: Refactored `TransformedOutput` to use a `HashMap` for grouping rows by `ContextOpt`, allowing for per-row configuration options. Updated methods in `PipelineExecOutput` to support the new structure (`src/pipeline/src/etl.rs`).
- **Add New Transformation Method**: Introduced `transform_array_elements_to_hashmap` to handle array inputs with per-row `ContextOpt` in `HashMap` format (`src/pipeline/src/etl.rs`).
- **Update Pipeline Execution**: Modified `run_custom_pipeline` to process `TransformedOutput` using the new `HashMap` structure, ensuring rows are grouped by `ContextOpt` and table name (`src/servers/src/pipeline.rs`).
- **Add Tests for New Structure**: Implemented tests to verify the functionality of the new `HashMap` structure in `TransformedOutput`, including scenarios for one-to-many mapping, single object input, and empty arrays (`src/pipeline/src/etl.rs`).
