Tutorial for s3 and aws

[akranga]

Create S3 Bucket component

We need to create as simple as possible tutorial for Terraform. This tutorial should lead user further. They will need to create a stack that requires aws and a component that requires to have aws and component

This component should produce a bucket that exposes well known parameters (TODO need link to the doc with common parameters for buckets)

• [x] Create s3bucket component that uses Terraform based on https://registry.terraform.io/modules/terraform-aws-modules/s3-bucket/aws/latest
• [x] Component should have a private ACL by default passed to the component as a TF_VAR_* variable
• [x] Component should have a bucket name that defaults to hub.stackName parameter which defaults to HUB_STACK_NAME environment variable on a stack level. This variable will trigger auto-generated name for bucket
• [x] Bucket should output parameters similar to gsbucket component with exception of access and secret key
• [x] Create tutorial that guides user through this and explains meaning of HUB_STACK_NAME parameter (need link to the doc)
• [x] Tutorial should explain though the aws/configure steps why this is important
• [x] Create a separate documentation article about common parameters for buckets
• [x] Capture terraform outputs fromTfVar

Bucket input parameters

• bucket.region
• bucket.name
