Update benchmarking clearCache routine to be able to preserve sslhostinfo:

related entries.

* The clearCache() API is part of the benchmarking extension.
* Modified clearCache() to take an argument so that we can selectively
  clear SSL information or not.
* The actual clear data call used to just call DoomAllEntries.  It still
  does that for clearing everything.  If preserving the ssl host entries,
  however, it will enumerate the cache.  Ran into cache invalidation upon
  calling doom, which makes the clear inefficient, but functional.

BUG=none
TEST=none
