[@aws-cdk/assert] Assertions library for Python

[srethira]

@aws-cdk/assert is only available in Typescript and Javascript. Would like this feature to be supported in Python for Unit and Integration testing.

While trying to build my an assertion library in Python I've found out that the aws-cdk.cloudformation-diff packages is not exported to other languages.

Making it available would be useful to build a consistent assertion library in python and other languages.
The language-specific assertion libraries could then be built mimicking the same design of the embedded Typescript one.

As more and more languages are supported by CDK, a consistent infra testing experience is 100% needed. I thought there already was an issue or an RFC for a multi lang assert library from 2018/19 but I can't find it now. It may be this on the rfc aws/aws-cdk-rfcs#4

Thanks @nideveloper and others. We've heard this feedback from customers and intend to make this available for all our supported languages.

The work involved is non-trivial, so it may be a bit of time before we can get to this.

yep, otherwise Typescript is the only runtime that is fully supported

This work is complete. Please use the new module '@aws-cdk/assertions' that is available in all languages.
