feat: support download persistent cache task from parents

[gaius-qi]

Description

This pull request includes several updates and improvements to the dragonfly-client project, focusing on enhancing the persistent cache functionality and improving error handling. The most important changes are summarized below:

Persistent Cache Enhancements:

• Added multiple new methods to the Storage implementation in dragonfly-client-storage/src/lib.rs to handle persistent cache pieces, including methods for starting, finishing, failing, uploading, and checking the existence of persistent cache pieces. [1] [2]
• Updated the IDGenerator implementation in dragonfly-client-util/src/id_generator/mod.rs to generate a more robust persistent cache task ID using SHA-256 hashing.

Error Handling Improvements:

• Modified the DfdaemonDownload implementation in dragonfly-client/src/grpc/dfdaemon_download.rs to use send_timeout for error messages, ensuring that errors are handled within a specified timeout period. [1] [2] [3] [4]
• Improved error logging and handling for persistent cache tasks in the DfdaemonDownload implementation, including more descriptive error messages and additional error handling for failed tasks. [1] [2] [3] [4]

Configuration Updates:

• Updated the Cargo.toml file to use version 2.1.11 of the dragonfly-api crate.
• Enhanced the DfdaemonUploadServer configuration in dragonfly-client/src/grpc/dfdaemon_upload.rs by adding TCP and HTTP2 keepalive settings.

These changes collectively improve the robustness, reliability, and maintainability of the dragonfly-client project.
