Update lambda binary

Build including:

- upgrade of tantivy with MANY performance improvements.
- a bugfix in chitchat catchup mechanism: less grpc chitchat rpc should be necessary
- improvement in the shard rebalancing mechanism. Shards should be more balanced amongst ingesters.
- aggregation limits will be shared accross requests (!). Searcher should be less likely to OOM, but more request might error.

A release to test lambda search

Moving lambda execution to the leaf.
