Support Resource: arn:aws:states:::lambda:invoke

[andrhamm]

This is a Feature Proposal

Description

With the new Context Object it is possible to define a state with a resource of Resource: arn:aws:states:::lambda:invoke. This is similar to the callback pattern but without the .waitForTaskToken suffix. Specifying the function arn in the Parmeters.FunctionName in this way (as opposed to in Resource) allows you to then also modify the Parameters.Payload property, optionally referencing values from the context object using $$.

Example:

GetExecutionName:
  Type: Task
  Resource: arn:aws:states:::lambda:invoke
  Parameters:
    FunctionName: arn:aws:lambda:us-east-1:1234123412341234:function:my-service-dev-myFunction
    Payload:
      ExecutionName.$: "$$.Execution.Name"

It looks like this might be as simple as adding an additional case here like so:

case 'arn:aws:states:::lambda:invoke':
case 'arn:aws:states:::lambda:invoke.waitForTaskToken':
    return getLambdaPermissions(state);
