Support for tags in Amazon API Gateway

[arabold]

This is a Feature Proposal

Description

On AWS tags are commonly used for logically associating resources with each other and simplifying billing. Amazon's API Gateway stages support tags now 🎉. However, those don't seem to be populated by Serverless yet:

Serverless already supports tags for Lambda functions as well as a stack-wide tags (stackTags). As an API Gateway stage can only have one set of tags I suggest to automatically assign the stackTags to the API Gateway stages during deployment.
