Recursively format HCL2 files.
hcl2fmt formats all HCL files recursively from current working directory
hcl2fmt -w dir formats all HCL files recursively with dir as the base path
It's a tiny tool, but being a Golang newbie I looked at both https://github.com/fatih/hclfmt and https://github.com/gruntwork-io/terragrunt fmt subcommand for tips and inspiration.
