tfstate should be stored in a central bucket

[mckayjuk]

Uploading tfstate to git causes an number of issues if muliple changes are applied by different people.

Fixed - Writing to S3 Bucket using terraform config block

# Configure Terraform 
terraform {
  backend "s3" { # Use the noted S3 bucket to store state
    bucket  = "bucke-name"
    key     = "tfstate/terraform.tfstate"
    region  = "eu-west-1"
    encrypt = "true"
  }
}

Modified slightly per terraform config. Keeping all tfstate files under same bucket but
