Add a Lambda+Codepipeline Typescript example #269

I'm adding an example here that deploys a Lambda+ApiGateway setup using CodePipeline.

Although there's plenty of examples of Lambda already, deploying them via CodePipeline had some non-trivial challenges to sort out. This could mean teams start using CDK and like it, but drop it because they can't adopt Full CI/CD easily when using it

Fixes #267

Looks excellent! My main concern is that some of the syntax choices were not consistent. Once thats fixed I'm happy to merge!

Please be consistent with semicolons. We recommend all lines terminate with semicolon, but if you want to follow the no-semicolon TS guidance, stick to that throughout the example.

@NGL321 The build seems to be failing with the following error:

> widgets-lambda@1.0.0 build /Users/seoaneg/Workspaces/aws-cdk-examples/typescript/lambda-api-ci/cdk.out/asset.5d8ebe4e1b7da78e3a974de62e8d9aac8a42747f5c303e249b6d1e2855c6e92f
> tsc

npx: installed 202 in 17.326s
--app is required either in command-line, in cdk.json or in ~/.cdk.json

widgets-lambda is the name of the NPM package I created under typescript/lambda-api-ci/src for the Lambda function. It seems the build is mistaking it for a CDK package. Do you know if I can exclude it somehow?

This commit adds an example that deploys a Lambda+ApiGateway setup using CodePipeline.

I've run the following commands to compare the directories that are evaluated:

find typescript -name package.json  | grep -v node_modules | xargs -n 1 dirname | sort
find typescript -name cdj.json  | grep -v node_modules | xargs -n 1 dirname | sort

Here is the diff. Directories removed are shown in grey on the left-hand side:

These directories are now excluded as they're Lambda NPM packages, not CDK packages:

Thank you for the catch! I had not noticed this. The fix is logical and LGTM.

@NGL321 Looks like mergify discarded your approval after the rebase. Can you take another look?
