Local environment with RIE and funcion names

Hi,

I have been using your interface extensively to build a suite of Lambda apps. Our architecture encompasses several Lambda functions, that are supposed to talk to each other via the [boto3](https://boto3.amazonaws.com/v1/documentation/api/latest/index.html) Python client. Thus far, I'm handling everything with HTTP ports on localhost, having a slightly different code base from the actual one that will be hosted on AWS.

Is it possible to have named Lambda functions within RIE, in order to use `invoke` calls via the boto3 Python client?

首先检查 RIE 对本地 HTTP 调用的行为，以及 boto3 的 `invoke` 使用场景。确定如何表示命名的 Lambda 函数，并在本地进程之间路由这些函数；当多个本地运行的函数可以通过 boto3 相互调用，而无需单独的 HTTP 专用代码路径时，即视为完成。
