Jason Tedor 9aae2f593a Avoid stack overflow on search phases ... When a search is executing locally over many shards, we can stack overflow during query phase execution. This happens due to callbacks that occur after a phase completes for a shard and we move to the same phase on another shard. If all the shards for the query are local to the local node then we will never go async and these callbacks will end up as recursive calls. With sufficiently many shards, this will end up as a stack overflow. This commit addresses this by truncating the stack by forking to another thread on the executor for the phase.
