Add a split task between the ELI Expression/Work extraction and translation. This allows the job-splitter to create one task per extracted expression resource.

The PDF pipelines currently create a single task per step. Such tasks may cover multiple PDFs and many decisions. Consequently, it difficult to selectively restart, for example, the enrichment for a specific decision after it failed. This would require either restarting the task as a whole, redoing to work for all resources, or manually starting a new job.
Therefore, this PR adds the annotation-job-splitter service to the existing PDF pipelines. This splits the tasks into smaller ones, e.g. per ELI expression, that can be more easily restarted.
Approach
The app contains to pipelines that involve PDFs:
pdf-to-eliandpdf-to-enriched. For both we add a new split task in between the initialsingleton-joband thepdf-scrapingtask. This split task allows the job-splitter service to create one task per URL the user provided as input.Furthermore, the
pdf-to-enrichedjob is extended with a second split task between itspdf-to-elistep andtranslatingstep. This allows the job-splitter service to create atranslatingtask per ELI Expression that was extracted in the preceding step. This way the job-controller service will take of creating the appropriate follow-up enrichment tasks, similar to other enrichment pipelines.How to test
annotation-job-splitterand re-up the service.job-controllerandannotation-job-splitterservices such that they load the modified configurations:docker compose restart job-controller annotation-job-splitter.Related PRs
