- Add an `AsyncLambdaHandler`. Will be renamed to `LambdaHandler` as soon as we drop the current callback based `LambdaHandler`.
- The default way to use an `AsyncLambdaHandler` is to use `@main` to execute it. Don't use `Lambda.run` for it. We wan't to remove `Lambda.run` for 1.0.

Add `@inlinable` to default LambdaHandler implementations. This ensures that those implementations can be inlined into user code and can be specialized for their input and output types.
Modifications:
- Replace `HTTPHandler` with `NIOHTTPClientResponseAggregator`, to fix a CoW issue. This increases performance.
- Ensure that we only use one `EventLoop` in tests.
- Use `syncOperations` to setup the `HTTPClient`.
motivation: in error cases where lamnda fails to start the process fails silently and exists with code 0
changes: change the blocking API to check on the result and fatalError if lambda cannot be started / run
motivation: more correct Xray TraceID
changes:
* add AmazonHeaders::generateXRayTraceID
* Generate correct trace ID in LocalLambda Server
* Generate correct trace ID in LambdaRuntimeClientTest
motivation: make shutdown easier to use
changes:
* override shutdown to use the offloadQueue to perform syncShutdown
* add empty syncShutdown that can be implmented by the concrete Lambda function
* allow the users of client to provide headers
* add initialization error header
* add error header to failed invocations
* fix external setting of ip and port via config
* add tests
motivation: in more complex initialization scearios you may want access to a logger or other utilities
changes:
* introduce new InitializationContext type that could be extended in the future without breaking the API in semantic-major way
* instead of passing in EventLoop to the handler factory, pass in a context that includes a Logger, an EventLoop and a ByteBufferAllocator
* fix a bug where we dont hop back to the event loop when coming back from the handler
* adjust tests to the new signature
motivation: better mock server
changes:
* add handler for :requestID/error
* return .accepted to lambda
* return .internalServerError to client + error json
* small refactoring of response code in mock server to make it DRYer
motivation: make using the local debugging server easier to turn off/on without the need to change code when oyu are preparing to deploy
changes:
* add code to lambda so that in debug mode only, if the LOCAL_LAMBDA_SERVER_ENABLED env variable is set the local debugging server is started
* make withLocalServer internal
* update example code
motivation: allow end to end testing locally
changes:
* add a Lambda+LocalServer which exposes Lambda.withLocalServer available only in DEBUG mode
* local server can receive POST requests with payloads on a configurable endpoint and and send them to the Lambda
* move Lifecycle completely into EventLoop
* remove all locks since running in one EventLoop
* Use UUID for requestId
