FloatSumAggregatorFactory, FloatMinAggregatorFactory and FloatMaxAggregatorFactory have identical equals() that could be moved to SimpleFloatAggregatorFactory

Since #4491. FYI @b-slim

@leventov why it need to override hashCode ? it is implemented at SimpleFloatAggregatorFactory can you please explain the bug ?

[leventov]

@b-slim indeed, it's a false-positive IntelliJ warning. However it highlights the fact that FloatSumAggregatorFactory.equals(), FloatMinAggregatorFactory.equals() and FloatMaxAggregatorFactory.equals() are identical, and it could move moved to method SimpleFloatAggregatorFactory.equals().
