benchmark: allow benchmarks to specify flags

* Give createBenchmark and the Benchmark constructor
  a third argument for specifying the command line flags
  that this benchmark should be run with.
  The benchmarks are no longer run with --expose-internals
  by default, they will need to explicitly pass the flags.
* Rename options to configs in createBenchmark and the Benchmark
  constructor to match the documentation since they are not optional.
* Comment the properties of a Benchmark object

Also improve the documentation about creating benchmarks

* Add detailed description of the arguments of `createBenchmark`
* Describe the two passes of running the benchmarks
* Suggest what kind of code should go where in the benchmark example
