Add collection IDs to relevant text reuse passages

[theorm]

To enable filtering of text reuse clusters by user collections we have added a collection filter that works with the ucoll_ss field in tr_passages index. At the moment Maud added a couple of test collections to the development index in preprod Solr. We need a celery job that would update text reuse passages when collections are created/changed. We will also need to tag passages with collections that have already been created (possibly a small script?).

PS: memo for @e-maud : check rights (r/w) on this index for c2dh user.

Actions:

• Maud ingest TR data in a SOLR prod (current app in prod points to dev SOLR)
• Maud allows c2dh writer on passages indexes (dev and prod)
• Daniele prepares bulk script
• Daniele ingest coll IDs to the newly ingested TR data in prod (and in dev for test if needed)
• Daniele sets up the celeri task
• Matteo tests everything :)
