A few things need to be added/cleaned up before the v0.1.0 release:

• integration tests (these are started for folder @ folder_v1 but need some for direct executor as well)
• documentation (usage, examples of backup and restore for all supported backends, section on why most should never use this tool, architecture, extension points, why you have to feed some data by env to subcommands)
• full e2e test that uses a dockerized redis instance (dockertest) and the binary itself
• rename binary to rbb
