Title: Add node-purge-ttl setting to purge deactivated nodes

During garbage collection, this will delete nodes which have been deactivated for at least the node-purge-ttl amount of time. Deletion of nodes will also delete their associated catalogs, facts and reports. This setting is off by default, and is only recommended to be used by users with a high level of node thrash, which will accumulate lots of old data.
