MICRO-41: Implementation of resource export

[kai-nguyen-aligent]

This is the first implementation of serverless-export-resources plug-in. This plug-in allow us to exports Lambda or Step Function arn and description with a predefined prefix.

Serverless configuration

• Though does not requires in the serverless configuration, this plugin will throw errors if the description of the exported resources are not available.
  • Lambda Function description can be set in the function declaration like so:

    functions:
      hello:
        handler: src/hello.handler
        description: >-
          This is a long dummy description of this Hello Lambda service to test the limitation of this export value. 
          It can contain up to 256 characters.

  • Step Function supports setting Comment which can be used as description:

    stepFunctions:
      stateMachines:
        stateMachine:
          name: ${self:service}-${self:provider.stage}-stateMachine
          definition:
            Comment: >-
              This is a very long dummy description of this State Machine service to test the limitation of this export value.
              It can contain nearly 500 characters.

• The plugin is configured within the serverless.yaml by providing configuration values as the example below

  custom:
    exportResources:
      functions: [hello, world]
      stateMachines:
        - helloWorld

Variables
