/// A module cache class.
///
/// Caches locally modules that are downloaded from remote targets. Each
/// cached module maintains 2 views:
///  - UUID view:
///  /${CACHE_ROOT}/${PLATFORM_NAME}/.cache/${UUID}/${MODULE_FILENAME}
///  - Sysroot view:
///  /${CACHE_ROOT}/${PLATFORM_NAME}/${HOSTNAME}/${MODULE_FULL_FILEPATH}
///
/// UUID views stores a real module file, whereas Sysroot view holds a symbolic
/// link to UUID-view file.
///
/// Example:
/// UUID view   :
/// /tmp/lldb/remote-
/// linux/.cache/30C94DC6-6A1F-E951-80C3-D68D2B89E576-D5AE213C/libc.so.6
/// Sysroot view: /tmp/lldb/remote-linux/ubuntu/lib/x86_64-linux-gnu/libc.so.6
