hclfmt is a public archive now. and terragurnt provides the command line utility to format the hcl files. this pull request will allow to use the command line similar to terraform to reformat the files.

@mochaaP Thanks for merging the pull request. I created this pull request as terragrunt formatting is similar to terraform formatting. However, not sure if i missed something or i need to add something. but formatting is not working.

however, seems like the command is getting timed out. is there a way to fix this ?
