* Added cache updating behavior for GetShard
Customer are occasionally seeing messages about being unable to
retrieve shard information, which is logged as a warning. This change
will allow the shard map to be updated even when there is no re-shard
operation.
This now triggers a shard list update if there is 1000 cache misses,
or a cache miss occurs when the cache is more than 30 seconds old.
For Kinesis the updates will use ListShards, and for DynamoDB Streams
it will continue to use DescribeStream.
* Adjust some logging, and the zeroing of cache misses a bit
Only log about cache refresh if it's the thread doing the cache
refresh. If after synchronizing the shard is present, accept that
someone else loaded the shard map, and move on.
If the cache was reloaded, and the shard was found the current thread
will reset the cache misses.
The warnings for the cache miss was using a modulo of 1000 which is
the maximum value for cache misses, so wasn't to useful.
