Add support for the AWS CDK CLI

[DerrickF]

We want to use the AWS CDK to generate our cloudformation templates.

This could be accomplished manually using a generic powershell task (given the CDK cli is installed) but the best thing (and the thing I like most about the plugin you've created) is the way it automatically pulls in credentials from our account. This makes handling the different credentials for our various AWS accounts and build environments SO much easier and makes key rotation a non issue for us.

Installing the cdk cli with npm prior to running this task returns: "The term 'cdk' is not recognized as the name of a cmdlet, function, script file, or operable program."

Definately this should be a must.

What I did as a workaround is use aws shell script task, install cdk with npm in the beginning and then use it as this task also gets the credentials from a service connection.
