/**
* This tests checks that repair database works and doesn't leave the database in a bad state
* 1.) Drop "repairDB" database
* 2.) Ensure repair works with single collection with an extra index. and one doc
* 3.) Ensure repair works with no docs, same collection/index as above
* 4.) Ensure repair works with 2 collections, one doc in each
* 5.) Ensure repair works on the local db (special cases)

* @tags: [
* requires_non_retryable_writes,
