[SPARK-15735] Allow specifying min time to run in microbenchmarks
## What changes were proposed in this pull request?
This makes microbenchmarks run for at least 2 seconds by default, to allow
some time for jit compilation to kick in.
## How was this patch tested?
Tested manually with existing microbenchmarks. This change is backwards
compatible in that existing microbenchmarks which specified numIters per-case
will still run exactly that number of iterations. Microbenchmarks which
previously overrode defaultNumIters now override minNumIters.
