Rudder

There is no garbage collection on inventories. The idea was that it was good to find if a node/inventory have had an inventory processed at some point. But I clearly see how it is useless to keep them all, and even dangerous (ever growing directories are generally not a so good idea).

So, what wouls you think be a good clean-up frequency? Configurable or not?

Without too much thinking, it seems that deleting inventories older than 1 month would be ok as a default, with an user configurable option in the admin screen.

Now that we store node content in `/var/rudder/fact-repository/nodes`, we should just delete inventories older that say 1 month in inventories sub directories.

Both /var/rudder/inventories/{incoming,accepted-nodes-updates} are housekept along with new inventories (the batch that look for inventories missed by inotify).
