Command history is handy, but it doesn't live beyond a session. It would be awesome if vantage had persistent history. As of now, this can only be achieved by loading entries into vagrant.session._hist.
History could be kept server-side on a per-user basis, or client-side on a per-host basis.
For a server-side implementation, instead of bundling this functionality with vantage itself, a public history API could be exposed for extensions to manage and provide history, with session history as the default implementation.
A client-side implementation could provide a vantage command-line flag to pick a history file, defaulting to something like ~/.vantage/history/<host> (for system-wide, per-host history) or ./vantage/history (for directory-based history).
