Title: refactor Vault::Config and make defaults

- Overrides unused Ruby `Config` constant with the `Vault::Config` class
- Add `Vault::Config::default` method so we can consolidate default values.
- Add `Vault::Config::[]` method so we can have uniform access (you get the default or whats in the ENV).
