SERVER-46395 Ensure range deletion task document exists during deletion.
Changes the range deletion task to guarantee a batch of documents can
only be removed while the corresponding range deletion task document
exists. If the range deletion task document doesn't exist or a stepdown
could lead to it not existing, then the range deletion task is
abandoned.
Changes the deletion of the range deletion task document to use the _id
index of the config.rangeDeletions collection rather than being a
collection scan.
