{{{NodeUtils.GroupSource}}} is already able to cache external call results, but with no time limit. This is OK for most one-shot commands like {{{clush}}} or {{{nodeset}}} but can be very annoying for long-term running apps or daemons using the ClusterShell library.

Implement:
* a method to flush cached results on demand,
* a configurable time limit for cached results, and if necessary, see if an external call or other way to check for cache info validity could be added.
