**Is your feature request related to a problem? Please describe.**
Include support for AWS SQS queues

**Describe the solution you'd like**
It would be great if Amplify Cli would support creating AWS SQS queues as resources, assigning a Lambda trigger from existing (or new) functions and providing permissions to other Lambdas to send messages to such queue.

**Describe alternatives you've considered**
So far I am using amplify to create the lambda that will work as the trigger and I have to create, manually and after pushing the environment, the queue and the trigger to such lambda. I also need to provide manually the permissions to the lambdas that are going to be sending messages to such queue.

**Additional context**
This si great for building more complex solutions and architectures using amplify.
