Upgrade Instructions:
The profile()-Step has been refactored into 2 steps - the ProfileStep and
the ProfileSideEffectStep. Users who previously used the profile()-Step in
conjunction with cap(TraversalMetrics.METRICS_KEY) can now simply omit the cap
step. Users who retrieved TraverseralMetrics from the side effects after
iteration can still do so, but will need to specify a side effect key when
using the profile()-Step.
CHANGELOG
Split existing profile()-Step into ProfileStep and ProfileSideEffectStep.
profile()-Step now emits TraversalMetrics without the need for cap()-Step.
3 I'm guessing this is outside the coverage of the tests? I'm not hooked up
to run Giraph or Spark (and don't have time to go down that rabbit hole). I
could definitely use some help here if testing those is required for merge.
