/*
*	This function must be implemented by any plugin because it is part of the
*	plugin interface defined by the core CLI.
*
*	Run(....) is the entry point when the core CLI is invoking a command defined
*	by a plugin. The first parameter, plugin.CliConnection, is a struct that can
*	be used to invoke cli commands. The second parameter, args, is a slice of
*	strings. args[0] will be the name of the command, and will be followed by
*	any additional arguments a cli user typed in.
*
*	Any error handling should be handled with the plugin itself (this means printing
*	user facing errors). The CLI will exit 0 if the plugin exits 0 and will exit
*	1 should the plugin exits nonzero.
