Implement HaeinsaConfiguration

[eincs]

Several constants are declared in HaeinsaConstants now, so that user can't modify those properties. To configure those properties, such as qualifier of lock column and lock timeout, we needs the class such as HaeinsaConfiguration.

See example of implementation:

// Configure properties of Haeinsa
// If user don't set value, Haeinsa will use default value
HaeinsaConfiguration conf = new HaeinsaConfiguration();
conf.setRowLockColumnQualifier("lock");
conf.setRowLockColumnFamily("!lock!");
conf.setRowLockTimeout(TimeUnit.SECONDS.toMillis(5));
conf.setRecoverMaxRetryCount(3);

// Pass HaeinsaConfiguration to HaeinsaTransactionManager
HaeinsaTransactionManager tm = new HaeinsaTransactionManager(tablePool, conf);
HaeinsaTableIface table = tablePool.getTable("test");
