Version 2.0.0

🎉 🎉 🎉

This is a major re-write of the Hummingbird server framework using structured concurrency. Below is a list of the larger changes

• Rebuild server on top of Swift NIO communication layer (NIOAsyncChannel) between their own EventLoop based APIs and structured concurrency.
• Removed all Swift NIO EventLoopFuture internals.
• Reimplemented TLS and HTTP2 libraries.
• Rewrote router and heavily optimised it.
• Added user-defined generic context to be passed alongside requests through router.
• Add support for streamed request payloads using AsyncSequences and streamed response payloads using a output writer.
• Added result builder middleware stack.
• Used result builder middleware stack to write a result builder based router in HummimgbirdRouter library.
• Use new HTTP types from Apple.
• Added integration with Service Lifecycle package. Application conforms to Service and uses graceful shutdown handlers.
• The ability to extend the Application type has been removed. Instead it recommended to use dependency injection.
• Similarly the ability to extend Request has been removed. Instead you should use the RequestContext generic parameter.
• Moved HummingbirdCore libraries into Hummingbird package.
• Merged HummingbirdFoundation library into Hummingbird library.
• Renamed HummingbirdXCT to HummingbirdTesting.
• HummingbirdJobs library has been broken out into it's own package swift-jobs.
• The HB prefix on all the symbols has been removed.

To help with moving from Hummingbird 1.0 we have written a migration guide.
