Mass-Resaving meta data files

[henning-gerhardt]

Is your feature request related to a problem? Please describe.
With #6815 it is now possible to re-save the meta data files for a list up to 10.000 processes to fix the invalid meta data files. As there is a current search limit of 10.000 processes it is very complicated and time consuming to iterate over hundred thousand of processes.

Describe the solution you'd like
It would be really nice to have an option to re-save the meta data files project wise so you can iterate over existing projects. If a re-save on this mass working is failing this should not mean that other outstanding processes of this selected project are skipped. There should be some kind of reporting function which list this failed processes. The list in the task manager - if executed over the task manager - is not good enough for this kind of reporting as only a configured limited amount of failed executed tasks are displayed.

Describe alternatives you've considered
You can fix the meta data files by f.e. a shell script on Unix/Linux with some tooling (xmllint for schema validation) but this is not executable in every environment and if an application support validating and some limited kind of repairing there should be even a way to to mass executions of this kind of repairing
