Instead of hard-coding a single cache directory and a set of refresh patterns, the *squid* role can now have custom cache rules defined with the `squid_cache_dir` variable (which now takes a list of `cache_dir` settings) and the `squid_refresh_pattern` variable (which takes a list of refresh patterns). If neither of these are defined, the default configuration is used. This is a breaking change, since `squid_cache_dir` used to refer to a directory, and the previous default was to configure one cache path. There are no extant users of this role, though, so it doesn't really matter.
