HACK: tolerate the mismatches from isolation tests

## Problem

Currently, if you need to rename a job and the job is listed in [branch
protection
rules](https://github.com/neondatabase/neon/settings/branch_protection_rules),
the PR won't be allowed to merge.

## Summary of changes
- Add `conclusion` job that fails if any of its dependencies don't
finish successfully

- * HyperLogLog is an approximate technique for computing the number of distinct

- * memory.  See the 2007 paper "HyperLogLog: the analysis of a near-optimal
- * cardinality estimation algorithm" for more.
- *
- * Instead of a single counter for every bits register, we have a timestamp
- * for every valid number of bits we can encounter. Every time we encounter
- * a certain number of bits, we update the timestamp in those registers to
- * the current timestamp.
- *
- * We can query the sketch's stored cardinality for the range of some timestamp
- * up to now: For each register, we return the highest bits bucket that has a
- * modified timestamp >= the query timestamp. This value is the number of bits
- * for this register in the normal HLL calculation.
- *
- * The memory usage is 2^B * (C + 1) * sizeof(TimetampTz), or 184kiB.
- * Usage could be halved if we decide to reduce the required time dimension
- * precision; as 32 bits in second precision should be enough for statistics.
