   How to test:
   
    * Create `n=1` and `n=2` dbs
    * Notice that custodian shouldn't emit errors
    * Set one of the nodes in maintenance mode. Custodian should emit errors.
    * Bring node back to production and kill one of the nodes. Custodian should also emit errors.
   
   ```
   http put $DB/n1db'?n=1'
   http put $DB/n2db'?n=2'
   ```
   
   ```
   config:set("couchdb", "maintenance_mode", "true", false).
   
   custodian:report().
   [{<<"n2db">>,{0,2147483647},{live,1}},
    {<<"n1db">>,{0,2147483647},{live,0}},
    {<<"_users">>,{2147483648,4294967295},{live,2}},

    {<<"_replicator">>,{0,2147483647},{live,2}}]
