Review Comment:
   could we refactor to
   ````
       protected final Map<FailableRunnable<MetaException>, String> tasks;
   ````
       in constructor:
   ````
   public AcidHouseKeeperService() {
       serviceName = this.getClass().getSimpleName();
       
       tasks = ImmutableMap.<FailableRunnable<MetaException>, String>builder()
         .put(txnHandler::performTimeOuts, "Cleaning timed out txns and locks")
         .put(txnHandler::cleanTxnToWriteIdTable, "Cleaning obsolete 
TXN_TO_WRITE_ID entries")
         .build();
   }
   
   private void cleanTheHouse() {

   ````
