Support setting custom HTTP headers

[waynexia]

This ticket requires a feature that exposes API(s) to allow setting custom HTTP headers for HttpBackend. Or exposes the underlying http_client like #4389

We now offer an HTTP client builder. Perhaps we could allow direct HTTP client integration, enabling OpenDAL to work with a wider range of HTTP clients.

We can add a new API called with(client: reqwest::Client) to allow users to build HttpClient via their own client. Would you like to give it a try?

[waynexia]

Sure, please assign 👍

By the way, the build API should work for now. Please try add headers in ClientBuilder and pass into http backend.

The current method of handling request headers seems incompatible with usage in other language bindings.

Yes, setting custom HTTP headers for other bindings is a seperate feature to support. Would you like to create an issue for this?
