+Feature: Predicate - typeOf()

+ Scenario: g_V_valuesXageX_isXtypeOfXGType_INTXX
+ Given the modern graph
+ And the traversal of

+ g.V().values("age").is(P.typeOf(GType.INT))
Review Comment:
It would be good to include a case that's uses typeOf to filter a stream of
mixed types as that will likely be the main use case here. We don't really have
graphs with mixed type properties, but something like this would be good:
```
g.V().values("age", "name").is(P.typeOf(GType.INT))
==> 29
==> 27
==> 32
==> 35
```

> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.4.2
> Reporter: Stephen Mallette
> Priority: Major
>
> Provide for a {{typeOf()}} predicate that allows for testing the type of an
> object which would enable neat things like:
> {code}
> g.V().outE().has('weight',gt(0.1)).inV().path().unfold().is(typeOf(VERTEX))
> {code}
> See the linked DISCUSS thread for more information.
