Add fromxcontent methods to index response (#22229)
This commit adds the parsing fromXContent() methods to the IndexResponse class. The method is based on a ObjectParser because it is easier to use when parsing parent abstract classes like DocWriteResponse. It also changes the ReplicationResponse.ShardInfo so that it now implements ToXContentObject. This way, the ShardInfo.fromXContent() method can be used by the IndexResponse's ObjectParser.
