TINKERPOP-1292: TinkerGraphComputer VertexProgramInterceptors
https://issues.apache.org/jira/browse/TINKERPOP-1292
Added `TinkerGraphCountStrategy` which will translate `g.V().count()` and
`g.E().count()` into direct calls to the underlying
`TinkerGraph.vertices/edges` hash maps (`.size()`). Thus, no need to iterate
out the vertices/edges and then count the iteration. O(1) time for count.
--- we can extend on this line of reasoning in this branch if people have
other ideas for shortcuts.
* Also did some cleanup of some test suites in Neo4jGraph and TinkerGraph
that should have been removed long ago when their respective strategy suites
were removed.

added TinkerCountGlobalStep and TinkerGraphCountStrategy which will turn
g.V().count() and g.E().count() into direct calls to the .size() of the
underlying TinkerGraph.vertices/edges Maps. Removed the OptIn strategy suites
in both TinkerGraph and Neo4jGraph -- this should have been done when these
suites were removed long ago.
