feat(imagebuilder-alpha): add support for Component Construct

[tarunb12]

Issue

aws/aws-cdk-rfcs#789

Reason for this change

This change adds a new alpha module for EC2 Image Builder L2 Constructs (@aws-cdk/aws-imagebuilder-alpha), as outlined in aws/aws-cdk-rfcs#789. This PR specifically implements the Component construct.

Description of changes

This change implements the Component construct, which is a higher-level construct of CfnComponent.

Example

const component = new imagebuilder.Component(this, 'Component', {
  componentName: 'build-and-test-component',
  componentVersion: '1.0.0',
  description: 'A build and test component',
  changeDescription: 'Initial version',
  // Encrypt component data with a KMS key
  kmsKey: kms.Key.fromKeyArn(
    this,
    'ComponentKey',
    this.formatArn({ service: 'kms', resource: 'key', resourceName: '1234abcd-12ab-34cd-56ef-1234567890ab' })
  ),
  platform: imagebuilder.Platform.LINUX,
  // Include the OS versions this component supports
  supportedOsVersions: [
    imagebuilder.OSVersion.AMAZON_LINUX,
    imagebuilder.OSVersion.RHEL_10,
    imagebuilder.OSVersion.SLES_15,
    imagebuilder.OSVersion.UBUNTU
  ],
  // Hello world component data
  data: imagebuilder.ComponentData.fromJsonObject({
    name: 'build-and-test-component',
    schemaVersion: imagebuilder.ComponentSchemaVersion.V1_0,
    phases: [
      {
        name: imagebuilder.ComponentPhaseName.BUILD,
        steps: [
          {
            action: imagebuilder.ComponentAction.EXECUTE_BASH,
            name: 'hello-world-build',
            inputs: {
              commands: ['echo "Hello build!"']
            }
          }
        ]
      },
      {
        name: imagebuilder.ComponentPhaseName.VALIDATE,
        steps: [
          {
            action: imagebuilder.ComponentAction.EXECUTE_BASH,
            name: 'hello-world-validate',
            inputs: {
              commands: ['echo "Hello validate!"']
            }
          }
        ]
      },
      {
        name: imagebuilder.ComponentPhaseName.TEST,
        steps: [
          {
            action: imagebuilder.ComponentAction.EXECUTE_BASH,
            name: 'hello-world-test',
            inputs: {
              commands: ['echo "Hello test!"']
            }
          }
        ]
      }
    ]
  })
});
