Re-introduce http::router (opt-in)

I am confused. There are a gazillion Rust routers, and they all now work with Spin because of the http compatibility. If we want Rust apps to have a router out of the box, why not make it a template option to reference a choice of third-party routers, like we do in JavaScript? I don't see the case for baking a gazillion-and-one-th router into the SDK - but happy to understand what I'm missing.

I share the same feeling but unfortunately after surveying the ecosystem I see alot of framework specific routers. Im sure there are other that are more general but the uptake of these pales in comparison to the hyper /Tokio specific crates. Another benefit to providing a simple bultin is that it should ease migration of apps from pre v6.

Love to see the re-introduction of the Spin HTTP router as it streamlines the DX for developers exploring Spin with little Rust knowledge.

Making the router optional, and adding a "idiomatic / common Router from the Rust ecosystem" would align with the JS/TS experience:

spin new foo-bar -t http-rust
