the class BrokerBookieIsolationTest method testStrictBookieIsolation.

/**
 * Validate that broker can support tenant based strict bookie isolation.

 * 2. namespace ns1 : has none group
 *    validate: bookie-ensemble for ns1-topics's ledger will be from bookies don't belongs to any group
 *    if bookies don't belongs to any group are not enough, then, throw #BKNotEnoughBookiesException
 * 3. namespace ns2,ns3,ns4: uses isolated-group
 *    validate: bookie-ensemble for above namespace-topics's ledger will try to select from isolated-group firstly
 *    if bookies belongs to isolated-group are not enough
 *    then, bookies from secondary isolation group will be selected (if secondary isolation group set)
 *    if bookies still are not enough, then, bookies don't belongs to any group will be selected.
