Tim Burke 5c6407bf59 proxy: Add a chance to skip memcache for get_*_info calls 
If you've got thousands of requests per second for objects in a single
container, you basically NEVER want that container's info to ever fall
out of memcache. If it *does*, all those clients are almost certainly
going to overload the container.

Avoid this by allowing some small fraction of requests to bypass and
refresh the cache, pushing out the TTL as long as there continue to be
requests to the container. The likelihood of skipping the cache is
configurable, similar to what we did for shard range sets.
