Add migration to reindex all issues
What does this MR do and why?
Reindex all issues by tracking every issue from the database.
The migration versions are forced to be before BackfillInitialEmbeddings because we have some documents in production which have an issue with es_id (more details in the linked issue) that's preventing the migration from completing. Once the reindexing migration is complete, then we will delete documents with old schema version and the embeddings migration will also complete.
