Support for Terragrunt Content Addressable Storage (CAS).

cas - What it does

Allow Terragrunt to store and retrieve Git repositories from a Content Addressable Storage (CAS) system.

The CAS is used to speed up catalog cloning, OpenTofu/Terraform source cloning, and stack generation by avoiding redundant downloads of Git repositories. When used with stacks, it also allows catalog authors to use relative paths in source attributes via the update_source_with_cas attribute.

<Since version="1.1.0"> This experiment flag is no longer needed, as the CAS is now enabled by default. Disable it with the `--no-cas` flag. </Since>
