Add a caching scheduler driver

This adds a new scheduler driver, CachingScheduler

It currently subclasses the filter scheduler and only adds caching of
calls to host_manager.get_all_host_states.

It relies on there being a small number of schedulers, ideally one,
calls to consume_from_instance within the filter scheduler to update the
current cached list of hosts, and a low rate of deletes.

It introduces the new config value:
scheduler_driver_task_period

The periodic task it controls is used by the caching scheduler to fetch
an updated copy of host_manager.get_all_host_states.

If your value for service_down_time is much smaller than
scheduler_driver_task_period, there will be issues with hosts appearing
to be dead, just because the list of hosts is being cached. Correct
configuration of those two values can avoid this issue.
