FEATURE: add dimensions hash to node event model

[andrehoffmann30]

I want to extended the history view of the package https://github.com/aertmann/history with a filter for the dimension. With this website admins get a much needed additional filter for the history view of a web site with several dimensions and dimension values. In preparation for the extensions of the https://github.com/aertmann/history package I created these changes to the node event model. Please let me know, if additional changes are needed. Thank you in advanced.

• Code follows the PSR-2 coding style
• Tests have been created, run and adjusted as needed

This might need a loooong time for larger node event tables (and they tend to get pretty large). It thought about how to delegate more of the work to the database. What about:

--pseudo code--

while $dimensionsArray = 'SELECT dimension FROM neos_neos_eventlog_domain_model_event where dimensionshash IS NULL LIMIT 1' {
    $dimensionsHash = Utility::sortDimensionValueArrayAndReturnDimensionsHash($dimensionsArray);
    $this->connection->executeStatement('UPDATE neos_neos_eventlog_domain_model_event SET dimensionshash = ? WHERE dimension = ?', [$dimensionsHash, $dimensionsArray);
}

Should work in O(n), with n = dimensionCombinations and should be much faster.

Hi @daniellienert , I adjusted the postUp function according to your suggestion. Can you please check, whether my adjustments are ok? Thank you.

Just reopened to trigger the pipelines again :)

Could you work on that for 8.3?

[andrehoffmann30]

Hi @markusguenther, yes I will take a look at it and rebase my changes onto the 8.3 code base.

[andrehoffmann30]

Hi @markusguenther I rebased my changes. Because I first rebased to the 8.2 branch and then to the 8.3 branch a tranalation from 8.2 is also in my changes which is missing in 8.3 at the moment. After 8.2 is upmerged into 8.3 this change should not be listed. Please check my changes and let me know, if something needs to be adjusted. Tnak you.

Thanks for the contribution :)

Maybe @daniellienert can add another review.
