Luca Cavanna 5818ff6b56 Make ShardSearchTarget optional when parsing ShardSearchFailure (#27078) ... Turns out that `ShardSearchTarget` is nullable, hence its fields may not be printed out as part of `ShardSearchFailure#toXContent`, in which case `fromXContent` cannot parse it back. We would previously try to create the object with all of its fields set to null, but `Index` complains about it in the constructor. Also made sure that this code path is covered by our unit tests in `ShardSearchFailureTests`. Closes #27055		2017-10-25 13:26:06 +02:00
