Add variables for re-index topic and re-index topic subscription
This one of MRs to fix the issue Use specific topic instead of the storage record change topic to send the re-index events
We should have 4 MRs to fix the issue:
- MR to create re-index topic/subscription
- MR to add the indexer-queue deployment variables
- MR to update the indexer-queue to handle messages from both re-index and record topics
- Last MR to update the indexer deployment variable (`reindex_topic_name') to use re-index topic
