use @aws-cdk/cloudformation-diff for diff generation

[AndrewChubatiuk]

Hi @nicka and @dougmoscrop
Thank you for a project. I've replaced json-diff with aws-cdk/cloudformation-diff to make visualisation more clear and upgraded some packages. I've published it as serverless-diff-plugin. Please let me know if you are okay with these changes

• replaced json-diff with @aws-cdk/cloudformation-diff
• added custom.diff.tableWidth (or DIFF_TABLE_WIDTH env variable) parameter to control IAM diff table width (useful for CI log output)
• generate diff even if there's no cloudformation template deployed
• upgraded old and deprecated dependencies
• package is being triggered automatically during diff command execution
• added custom.diff.excludes key to exclude some results from diff using jsonpath
• added custom.diff.reportPath key for gitlabci tfplan report generation

@bm1549 thanks
I’m currently supporting my fork. You can check it

@AndrewChubatiuk Are you still maintaining your fork? It looks like everything I've been wanting from this repo, but I can't get the diff working. It seems to always show a diff as if no resources have been deployed.

@mrchops1024 yes, still maintaining. I've enabled issues in a fork. Can you post a problem with configuration you're using?

Awesome work @AndrewChubatiuk!

@AndrewChubatiuk - I raised an issue in your fork but haven't seen any response. Thanks.
