Lei, HUANG 05b708ed2e feat: implement process manager and information_schema.process_list (#5865) 
* ### Add Process List Management

 - **Error Handling Enhancements**:

* refactor: Update test IP addresses to include ports in ProcessKey

* feat/show-process-list:
 Refactor Process Management in Meta Module

 - Introduced `ProcessManager` for handling process registration and deregistration.
 - Added methods for managing and querying process states, including `register_query`, `deregister_query`, and `list_all_processes`.
 - Removed redundant process management code from the query module.
 - Updated error handling to reflect changes in process management.
 - Enhanced test coverage for process management functionalities.

* chore: rebase main

* add information schema process list table

* integrate process list table to system catalog

* build ProcessManager on frontend and standalone mode

* feat/show-process-list:
 **Add Process Management Enhancements**

 - **`manager.rs`**: Introduced `process_manager` to `SystemCatalog` and `KvBackendCatalogManager` for improved process handling.
 - **`information_schema.rs`**: Updated table insertion logic to conditionally include `PROCESS_LIST`.
 - **`frontend.rs`, `standalone.rs`**: Enhanced `StartCommand` to clone `process_manager` for better resource management.
 - **`instance.rs`, `builder.rs`**: Integrated `ProcessManager` into `Instance` and `FrontendBuilder` to manage query

* feat/show-process-list:
 ### Add Process Listing and Error Handling Enhancements

 - **Error Handling**: Introduced a new error variant `ListProcess` in `error.rs` to handle failures when listing running processes.
 - **Process List Implementation**: Enhanced `InformationSchemaProcessList` in `process_list.rs` to track running queries, including defining column names and implementing the `make_process_list` function to build the process list.
 - **Frontend Builder**: Added a `#[allow(clippy::too_many_arguments)]` attribute in `builder.rs` to suppress Clippy warnings for the `FrontendBuilder::new` function.

 These changes improve error handling and process tracking capabilities within the system.

* feat/show-process-list:
 Refactor imports in `process_list.rs`

 - Updated import paths for `Predicates` and `InformationTable` in `process_list.rs` to align with the new module structure.

* feat/show-process-list:
 Refactor process list generation in `process_list.rs`

 - Simplified the process list generation by removing intermediate row storage and directly building vectors.
 - Updated `process_to_row` function to use a mutable vector for current row data, improving memory efficiency.
 - Removed `rows_to_record_batch` function, integrating its logic directly into the main loop for streamlined processing.

* wip: move ProcessManager to catalog crate

* feat/show-process-list:
 - **Refactor Row Construction**: Updated row construction in multiple files to use references for `Value` objects, improving memory efficiency. Affected files include:
   - `cluster_info.rs`
   - `columns.rs`
   - `flows.rs`
   - `key_column_usage.rs`
   - `partitions.rs`

   - `pg_namespace.rs`
 - **Remove Unused Code**: Deleted unused functions and error variants related to process management in `process_list.rs` and `error.rs`.
 - **Predicate Evaluation Update**: Modified predicate evaluation functions in `predicate.rs` to work with references, enhancing performance.

* feat/show-process-list:
 ### Implement Process Management Enhancements

 - **Error Handling Enhancements**:
   - Added new error variants `BumpSequence`, `StartReportTask`, `ReportProcess`, and `BuildProcessManager` in `error.rs` to improve error handling for process management tasks.
   - Updated `ErrorExt` implementations to handle new error types.

 - **Process Manager Improvements**:
   - Introduced `ProcessManager` enhancements in `process_manager.rs` to manage process states using `ProcessWithState` and `ProcessState` enums.
   - Implemented periodic task `ReportTask` to report running queries to the KV backend.
   - Modified `register_query` and `deregister_query` methods to use the new state management system.

 - **Testing and Validation**:
   - Updated tests in `process_manager.rs` to validate new process management logic.
   - Replaced `dump` method with `list_all_processes` for listing processes.

 - **Integration with Frontend and Standalone**:
