Subject: [PATCH] feat: display version info when starting daemon (#1915)

Similar to what go-ipfs is now doing this prints the js-ipfs version, system arch/platform and Node.js version when a daemon is started.

Repo version is not yet included (but also unnecessary right now as we don't have repo migrations yet).
