You need to set these to the values used in the AllowableValues.

The newValue value does not correspond to the enum values, so it blows up 3 
unit tests.

I don't think even needs to exist at this point because 
`routequeryInfoRels` effectively does all three use cases and only gets the 4th 
relationship based on the routing strategy. Might want to refactor that and 
change the name to be more appropriate to the overlap.

You have a lot of duplicate code here. You could move:

```
final Set routeQueryInfoRels = new HashSet<>();
routeQueryInfoRels.add(REL_SUCCESS);
routeQueryInfoRels.add(REL_FAILURE);
routeQueryInfoRels.add(REL_RETRY);
```

to before the if/else if blocks and then add `REL_QUERY_INFO` only in those 
two blocks. Also the `this.relationships` assignment could be done there as 
well.

Should we run this with both 1 and 0 for coverage? I haven't looked into

So, you are saying that, if you set it to NO_HITS and you get all 20 at a 
time, you get a query info on the last try?

This part doesn't quite work, not necessarily due to a logic error here, 
but it needs to be addressed either here or in the onTrigger do-while loop. If 
I don't set a limit and I set my page size to 20, then fetch all results (I 
have 100), then I get a flow file on the query-info connection. This is because 
the hitLimit variable is never set as the limit variable is always null, so we 
attempt to get all records starting from index 100, and zero are returned. 
However this code checks that hits.size() is zero (which it is the last time). 
No documents are output of course (due to the for-loop below), but the 
query-info flow file is sent. Perhaps this method needs to know the current 
total number of hits?

Just found out that some processors have used camel cases in writing 
attributes. Sorry about that. Feel free to revert back although `es.hitcount` 
itself looks good to me.

Having the attribute by default sounds fine to me, usually when we have a 
property to choose it's because the value in the attribute could be fairly 
large (such as a compound SQL query used in ExecuteSQL, e.g.).

I believe, in general, it is a standard practice in the project to avoid 
casing `WritesAttributes` so shall we change it to `es.hit.count` or 
`es.hitcount` ?

I believe "Generate Query Info" has to be changed to "Routing Strategy for

Should we really need to have a property for this? Writing the 
`es.query.url` as an attribute by default sounds safe to me. Thoughts?

I believe that will work. Also MockProcessContext calls onPropertyModified 
on set/removeProperty(), so you might be able to parlay that into a unit test 
to check that the relationship is available or not (but I'm not sure)

This whole if-else should be wrapped in a check to see if the 
PropertyDescriptor is the Query Info Strategy property. Otherwise, changing any 
other property results in entering this final else clause, thereby resetting 
the Query Info Strategy to "Never".

CheckStyle violation here, the ? should be on the next line. You can run 
your Maven build for the nifi-elasticsearch-bundle with the contrib-check 
profile activated (`-Pcontrib-check`) and it will run a style check for you.

NIFI-3576 Support for QueryInfo relationship, useful for nohit queries

This pr adds a new relationship, and a property/strategy for when it is 
used.
The new relationship has an empty flow file with attributes about the 
query, right now the query string and the number of hits.

The relationship is dynamically made available based on the strategy 
selected:

Never : um, never send query information
Always: always send it
NoHit: Send it when there are no hits.
