When measurements are inserted significantly out-of-order, buckets tend to be closed often, which leads to very inefficient bucketing, and often buckets with only one measurement. Additionally, after a restart, we effectively close all buckets and have to start bucketing over again.

Currently, once a bucket is closed and removed from the BucketCatalog, it may not be re-opened. Instead, a bucket should only be permanently closed if it is full.

If there is no suitable open bucket for a measurement, we should attempt to find a closed bucket, load it into the BucketCatalog, and insert more measurements.
