- Added support of `json` output for most commands through the usage of the global `-o`/ `--output-format` argument (to be given before any command).
- The default output remains the `human` format.
- Added possibility to use `vault inspect` command without interactive prompts (when providing all necessary arguments)
- To have a clean `json` output; those commands should be called with all necessary arguments so that no interactive prompt is required; which then allows to pipe the result to other commands like `jq`
