improvements. See changelog in https://pypi.org/project/ZEO/5.4.0/
for details.

Going from ZODB 5.6.0 to 5.8.0:

- removes leftovers of pre-MVCC read conflicts,
- relaxes assertion in tests that relate to NEO,
- brings up interface requirements in line with Wendelin.core 2 and WCFS,
- optimizes IO in fsrefs,
- fixes fsdump to match fsstats,
- provides new tests that exercise potential concurrency issues in
  storage implementations more thoroughly,
- provides other fixes and improvements.

Please see https://github.com/zopefoundation/ZODB/compare/5.6.0...5.8.0 and
https://pypi.org/project/ZODB/5.8.0/ for details.

Database password is now randomly generated.
Now test that the pre-filled password matches the mariadb url.

By inspecting current configuration stored in .data-disk-amount of the
partition configuration directory extend the conflict protection to really
observed configurations.

Adapt the README to follow real messages and explain a bit more the situation.

Patch 15e26abd explicitly declared
go version 1.17 for the 'helloworld' SR.

This was done at a time when we already had [golang1.17] in component/golang,
but the default was still go1.16. The explicit declaration allowed the 'helloworld' SR
to already switch to the newest go version.

Since patch d32524c3
we use go1.18 as our default version. In order to allow 'helloworld' to use our newest
SlapOS supported go version, it's therefore sufficient nowadays to simply remove the
explicit declaration.
