Cleanup comments
Make aae_test work with new schema storage

* Need to wait for the schema to be propagated via cluster meta.

* No longer need to add 3 to the repair count since schema is no longer
  stored in KV.
Fix index admin test, wait for schema before reload

Need to wait for the schema change to propagate to all nodes before
reloading the index. Otherwise it will use the old schema and the new
field will not be present causing the assert to fail.
