Upgrade to aws cdk v2

[hupe1980]

AWS Cloud Development Kit (AWS CDK) v2 is now generally available:

• https://aws.amazon.com/about-aws/whats-new/2021/12/aws-cloud-development-kit-cdk-generally-available/

We have to update to use v2:

Do you need any help with this?

@mbp Any help is welcome. So far I've only created the branch for the update.

I'm looking at doing cdk-chatops and cdk-developer-tools-notifications. One question.

Do the versions of the packages (in package.json) all need upping to reflect the difference in using CDK v2?

How do we update all these while

• not breaking it for existing users allow them to stick to CDK v1
• allow future fixes/changes to the CDK v1 code (and let those using the CDK v2 version not revert to CDKv1 versions)

looking at https://github.com/cdklabs/cdk-nag/tree/v2-main they have are upping the versions so users request ^2.0.0 for CDK v2 and ^1.0.0 for CDK v1

so should I take @cloudcomponents/cdk-chatops version 1.50.0 and make a 2.50.0 that is the same as 1.50.0 but using CDK v2?

You don't have to worry about the version in package.json. When the migration is complete I will publish a new major release.

@hupe1980 can you create the new major versions (as rc)? Apparently, you have already migrated the package I need @cloudcomponents/cdk-cloudfront-authorization and I'd like to use it already please.

Hi @hupe1980, What is left to complete the migration to CDK_V2, would be happy to help with anything particular.

@victorsibanda You can see the progress in the cdk2 branch and in #142. Any help is welcome.
