Support for ECHO in Lambda under the application load balancer. Create an adapter.

[ikegam1]

I am developing a Lambda under an application load balancer.
I want to use echo there.
I have an idea of where to modify it.
I think I can create a new adapter.go with a different name.

I will try to create a pull request in the near future.

Would you consider using this instead: https://github.com/awslabs/aws-lambda-web-adapter

@sapessi
Thank you!
But I don't know if that will support the echo Framework.

I want an adapter.go that can use the Application load balancer.
In this, I want to use events.ALBTargetGroupResponse instead of events.APIGatewayProxyResponse.

@sapessi could you please take a look at @ikegam1 's PR. It work very well and I already added (to my fork) support for fiber ALB on top of his PR.
