Cache doesn't count towards a subrequest afaik

kj::Own<CacheClient> IoContext::getCacheClient() {
  // TODO(someday): Should Cache API requests be considered in-house? They are already not counted
  //   as subrequests in metrics and logs (like in-house requests aren't), but historically the
  //   subrequest limit still applied. Since I can't currently think of a use case for more than 50
  //   cache API requests per request, I'm leaving it as-is for now.
  limitEnforcer->newSubrequest(false);
  return getIoChannelFactory().getCache();
}
