Allow using existing `cdk.out`

[wichert]

We use Python for CDK, and require some extra magic to handle AWS authentication. The end result of that is that to run CDK the real command I need to use is this: aws-woven-auth dev run poetry run cdk synth --all. This is of course highly specific to our environment, so cfn-diagram does not need to support that directly. What we do need to make the CDK integration work for us is an ability to either use an existing cdk.out directory, or be able to specify our own cdk command.

Thanks for reporting this @wichert

This use case makes sense. There was already an option for overriding the default cdk.out path (--cdk-output|-co)

However, using that did a cdk-synth in its place.

Based on other feedback I've had, I've now added an option to skip the synth step (--skip-synth|-s).

This lets you do something like
aws-woven-auth dev run poetry run cdk synth --all && cfn-dia HTML --skip-synth --cdk-output ./your-existing-dir

Will release this shortly

This has been released in v 1.1.15.

Please reopen if the issue persist

I'm not sure this works correctly. I have a cdk.out folder with 10 cfn templates in it. When I run npx @mhlabs/cfn-diagram@1.1.15 html -s -co cdk.out I only see the output from a single cfn template, instead of all templates.
