WIP: tablet: skip over gaps in rowsets using key index instead of bloom
This leverages the rowset-wise application of write ops to look for
"gaps" in the rowset where multiple insertions fall. For example, a
rowset might include keys like '1996-01-01...' and then skip to keys
like '1996-02-01...'. If a batch of writes comes with all rows falling
between those two keys, this patch allows us to more effiicently notice
that all of the writes are non-duplicate without doing per-op bloom
checks.
This is substantially faster for many workloads.
TODO: doc benchmarks, much cleanup
