rgw: Refactor checking of some ops

Since some operations check the user against the bucket owner in the
absence of a policy, rather than open-coding that everywhere, act like
a proper computer scientist and abstract it.

rgw: Plumb refresh logic into object cache

Now when we force a refetch of bucket info it will actually go to the
OSD rather than simply using the objects in the object cache.

rgw: Add expiration in the object cache

We had it in the chained caches, but it doesn't do much good if
they just fetch objects out of the object cache.

rgw: Expire entries in bucket info cache

To bound the degree to which an RGW instance can go out to lunch if
the watch/notify breaks down, force refresh of any cache entry over a
certain age.

Fifteen minutes by default, and expiration can be turned off entirely.

This is separate from the LRU. The LRU removes entries based on the
last time of access. This expiration patch forces refresh based on the
last time they were updated.
