Merge #27848 #28793 #28903

27848: sql: quantize the statement counts reported to the reg server r=knz a=knz

Fixes #25114.

This preserves every count smaller than 10, then for larger values
bucket into buckets that are powers of 10.

Release note (sql change): CockroachDB now hides more information from
the statement statistics reported to Cockroach Labs.

28793: storage: update the tscache appropriately after a merge r=tschottdorf a=benesch

@nvanbenschoten I figured this was in your wheelhouse but feel free to defer the review to @tschottdorf!

---

When applying a merge, teach the leaseholder of the LHS range to update
its timestamp cache for the keyspace previously owned by the RHS range
appropriately.

Release note: None

28903: closedts/transport: avoid race when using stopper.RunWorker r=tschottdorf a=benesch

Stopper.RunWorker cannot be called in code which can run concurrently
with Stopper.Stop. Use Stopper.RunAsyncTask instead.

Fix #28755.

Release note: None
