Review comment:
The more I think about it does it even make sense for the class itself to be
templated. Does the class itself depend in any way on the `TResult`. I think
the answer is no if you look at each method. The bulk of the methods are
factories for `Query<TResult>` and `CqQuery<TKey, TResult>`. So should have to
ask for a new `QueryService` every time I want to make new `Query` with a
different `TResult`? That seems wrong to me.
```
var qsString = cache.getQueryService<string>();
var qString = qsString.createQuery("....");
var qsInt = cache.getQueryService<int>)();
var qInt = qsInt.createQuery("...");
```
vs.
```
var qs = cache.getQueryService();
var qString = qs.createQuery<string>("....");
var qInt = qs.createQuery<int>("...");
```
