Proposal: Events property for AWS::SQS::Queue to implicitly define an API Gateway

**Description:**

It would be really handy the possibility to define an Event as a property when declaring an SQS resource, in order to implicitly define an API Gateway that sends the payload as a message into the queue.

This is a simple SAM Template example of what I'm talking about:
```
MyProjectQueue:
Type: AWS::SQS::Queue
Properties:
Events:
MyProjectApi:
Type: Api
Properties:
Path: /myproject/push
Method: post
```
**Current Behavior**
Of course, being `Events` not supported by SQS Queue, the deploy fails and I can see the following error using the command `aws cloudformation describe-stack-events --stack-name myproject-stack`

```

**Expected result:**
The expected result would be


Including the relevant policies. Exactly like it happens for a Lambda function
