Aws s3 state

[geronimo-iia]

Hello,

I had the need to retreive output state of terraform stored on s3 bucket, as we using it in a large system ...
Your base code is excellent to add this kind of feature.

So, i had made some change like:

• adding aws sdk dependency and s3 client
• add TFWorkspace class to manage several workspace usage in a single serverless configuration
• work on loading to switch to the right use case (s3 retreival or terraform command line)
• avoid adding "outputs" and "value" keyworkd on path definition

Let me known if you would integrate it in your current project or no. I wouldn't fork totally this project...

Thank in advance for your time,

Jerome
