TINKERPOP-1234: program() step that takes arbitrary vertex programs
https://issues.apache.org/jira/browse/TINKERPOP-1234
We now have `GraphTraversal.program(VertexProgram)`. This allows users to
do things such as:
```
g.V().out("bought").in("bought").program(CollaborativeFilteringVertexProgram.build()....)
```
Behaves just like any other `VertexProgramStep` where:
```
g.V().pageRank() == g.V().program(PageRankVertexProgram...)
```
CHANGELOG
```
* Added `GraphTraversal.program(VertexProgram)` to allow arbitrary user
vertex programs in OLAP.
```
VOTE +1. @dkuppitz tested it with his use case as well.

first stub of ProgramVertexProgramStep which is like TraversalMap in that
it VertexProgramStep that takes a Program.

simplified ProgramVertexProgramStep and added ProgramTest and
GroovyProgramTest. Its crazy, it 'just works'.

Added graph as a binding in ScriptTraversal much like g. This ensures that
when a ScriptTraversal references the graph, its there as graphs are not
serializable. This problem emerged during GroovyProgramTest on Spark and Giraph.

added hashCode() and toString() to ProgramVertexProgramStep.

> Components: process
> Affects Versions: 3.2.0-incubating
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
>
> In 3.2 VertexPrograms like {{PageRankVertexProgram}} will have a dedicated
> step that allows to do things like {{g.V().out().out().pageRank()}}. Would be
> nice to have a general step {{program()}}, so that we can do the same thing
> with any {{VertexProgam}}, e.g.
> {code}
> // pre-calculate "users who bought this, also bought" and create uwbt-edges
> for the top 100 results per vertex
> g.V().as("a").in("bought").out("bought").where(neq("a")).as("b").select("a","b").
>
> program(CollaborativeFilterVertexProgram.build().source("a").target("b").limit(100).edgeLabel("uwbt").weightProperty("weight").create())
> {code}
