The blob cache for searchable snapshots used default sync durability. Indexing into this often comes in bursts (multiple files for a shard or multiple shards for an index or even multiple indexes being mounted) and since it is immutable and easily reconstructed, this commit changes durability to async. This improves mount performance when blob cache index is co-located with the searchable snapshot(s).
