This looks good in general. The only issue we should consider is whether
having one IterationConfiguration type for both vertex-centric and GAS (and
probably other iteration models we might add in the future) is a good idea.
There are some options that all iteration configurations will share, like name
and parallelism, but there are also many model-specific settings, like
udf-specific broadcast sets and the options that #537 will introduce. Any
thoughts on this?
