Feature Request: Implement WebSocket Client in Seastar

[longyue188]

Hello Seastar Maintainers,

I'm currently using Seastar in my project and have noticed that it includes a WebSocket server but lacks a WebSocket client implementation. A WebSocket client is essential for full-duplex communication in many modern applications.

Feature Request:

• Implement a WebSocket client in Seastar.
• Ensure it is compatible with the existing WebSocket server and other Seastar networking components.

The addition of a WebSocket client would greatly enhance Seastar's capabilities, making it more versatile for various use cases.

Thank you for considering this feature request.

Best regards,
