AWS Gateway Load Balancer monitoring functionality must be added.

Hi LM

I had a request from one of our clients to set up monitoring and alerting for the gateway loadbalancers, but I couldn't find any documentation on that, and according to LM support, the functionality isn't currently available. 

I'd like to request you to please integrate this functionality as soon as you can.

Please refer the aws GWLB's documentation below.
