TTL for metric tree objects (ElasticSearch)

[dene14]

There is planned to set/update TTLs in ES, however after recent patch #36 'index/present' used to avoid excessive updates. This logic breaks an ability to maintain tree objects' TTLs properly.

Any ideas on how to maintain tree index now?

+1 to this question - is it a matter of crawling through the appropriate keyspace manually to prune? How are people approaching this?

@pdolan this is actually more of a question of attaching TTLs to inserts in elasticsearch documents

I'm moving this to the next release since the current codebase will need a bit more changes.

Now integrated in what will be 0.5.1
