This method is a shallow wrapper around manifeststore.NewStore, but
due to its signature resulted in various dependencies becoming a dependency
of the "command" package. Consequence of this was that cli-plugins, which
need the cli/command package, would also get those dependencies. It is no
longer used, and was deprecated in e32d5d56f5.
This patch removes the ManifestStore method from the interface
