Description

In system update plugin in Rudder 8.0, we were forced to build an ad-hoc cache for software updates with dedicated LDAP queries.

Given that, it seems that it should be part of CoreNodeFact and always be in memory, or, if we prefer to let the cache live only in system update plugin, have the specialized LDAP request built for it.

It we choose to add software updates to CoreNodeFact, we need to have a better guess at memory implication (how much memory for 15000 nodes with a mean of 200 updates ?).
And we will need to update node search and system update to use it.

SoftwareUpdate looks like it takes around 20kB per node for 200 updates. So we are talking about 300Mo for 15k nodes, it seems OK. We will try to add it, test in perf machine, and see how it behaves.
