Test Infra code for contributing

[GwonsooLee]

Is your feature request related to a problem? Please describe.
There is no test code before checking goployer works in local system. Also if someone ones to deploy with goployer in the AWS environment, ALB, TGs are needed before testing.

Describe the solution you'd like
Terraform code is needed

Additional context
Before considering local test, we should have pre-test environment for contributing.

@jupitersong, @asbubam
How about adopting CDK for test infra code?
https://docs.aws.amazon.com/cdk/latest/guide/getting_started.html

With AWS CDK, we can initiate installation of infrastructure for test in user's account. Of course we could provide terraform. Any opinion is welcome.
