* chore: add Noop Wal option
* remove: WalOptionsAllocator::alloc method
* feat/no-op-wal:
### Add Noop WAL Option
- **`engine.rs`, `opener.rs`, `wal.rs`, `entry_reader.rs`, `handle_write.rs`, `provider.rs`**:
- Introduced a new `WalOptions::Noop` variant to handle scenarios where no write-ahead logging is required.
- Implemented `NoopEntryReader` to provide a no-operation entry reader.
- Updated logic to skip WAL operations for regions with `Noop` option.
- Added `Provider::Noop` to handle `Noop` operations in the provider logic.
* feat/no-op-wal:
### Add `skip_wal` Option to Table Metadata
- **Enhancements in `table_meta.rs`**:
- Added a `skip_wal` parameter to the `create_wal_options` function to allow skipping WAL writes.
- Updated the `create_table_route` function to utilize the `skip_wal` option from `table_info.meta.options`.
- **Updates in `wal_options_allocator.rs`**:
- Modified `alloc_batch` to handle the `skip_wal` flag, setting WAL options to `Noop` when true.
- Added a test case `test_allocator_with_skip_wal` to verify the `skip_wal` functionality.
- **Changes in `requests.rs`**:
- Introduced `skip_wal` in `TableOptions` and added parsing logic.
- Updated `TableOptions` display to include `skip_wal`.
These changes introduce the ability to skip WAL writes for tables, enhancing flexibility in table metadata management.
* feat/no-op-wal:
**Add WAL Option Handling and Table Option Validation**
- **`handle_write.rs`**: Introduced a check for `WalOptions::Noop` in the `RegionWorkerLoop` to skip WAL writing for regions with this option.
- **`requests.rs`**: Added `SKIP_WAL_KEY` to the list of valid table options for enhanced table configuration validation.
* feat/no-op-wal:
### Update WAL Options Allocation
- **`key.rs`**: Modified the `allocate_region_wal_options` function to include an additional boolean parameter, enhancing the allocation logic.
- **`wal_options_allocator.rs`**: Simplified the `test_allocator_with_skip_wal` test by removing unnecessary variable declarations and directly using `WalOptionsAllocator::RaftEngine`.
These changes improve the flexibility and efficiency of WAL options allocation in the system.
* chore: reformat code
* feat/no-op-wal:
**Enhancement:** Conditional Addition of `SKIP_WAL_KEY` in `requests.rs`
- Updated `TableOptions` implementation in `requests.rs` to conditionally add `SKIP_WAL_KEY` to `key_vals` only when `self.skip_wal` is true, optimizing the key-value pair generation.
* feat/no-op-wal:
Update `requests.rs` tests to reflect changes in `skip_wal` option
- Modified test assertions in `requests.rs` to remove `skip_wal=false` from expected strings.
- Added a new test case to verify `skip_wal=true` is correctly represented in `TableOptions`.
* feat/no-op-wal: Add Debug Logging and Improve Error Handling for WAL and Table Options
• Introduced debug logging in wal.rs to skip obsolete regions, enhancing traceability.
• Improved error handling in requests.rs by replacing warn with error propagation for invalid skip_wal values.
• Added new test cases for skip_wal functionality, including SQL scripts and expected results, to ensure correct behavior and validation of the changes.
