Backend config file is not compliant with the canonical format when the S3 lockfile option is enabled @vonZeppelin (#193)
## what Generated backend config file is not compliant with the canonical Terraform format and style when the S3 lockfile option is enabled due to excessive indent. Additionally, the `use_lockfile` param is boolean, not string. ``` ...use_lockfile = "true"
## why
After formatting the generated file with `terraform fmt` command to follow the TF style, running `terraform apply` will revert the change.
