MINOR: don't log config during unit tests

[vvcephei]

The StreamsConfig class by default prints its configuration values during construction.

This is valuable at runtime as a record of the actual configuration, but during unit testing,
it results in excessive output.

@vvcephei thanks for looking into this.

I like setting the configs of during testing, but I think we can turn off logging during testing without the new class.

[bbejeck]

Could we do final StreamsConfig streamsConfig = new StreamsConfig(config, false); instead? I tried locally and it worked.

[vvcephei]

That works for TopologyTestDriver, but not MockProcessorContext because that constructor is protected, and the TopologyTestDriver happens to be in the same package as StreamsConfig.

I previously had the QuietStreamsConfig used only in MockProcessorContext, but the feedback was to also use it in TopologyTestDriver.

Seeing it this way, do you think it makes sense just to use the protected constructor in TopologyTestDriver, and the QuietStreamsConfig in the MockProcessorContext?

[bbejeck]

With the additional context, I'm fine with the PR as is.

[vvcephei]

Trunk should be fixed now.

Retest this, please.

[bbejeck]

failure unrelated

restest this please

[bbejeck]

LGTM

[vvcephei]

Thanks, @bbejeck !

[mjsax]

One nit. Overall LGTM.

[mjsax]

Why do we need an additional package? org.apache.kafka.streams.internals seems sufficient.

[vvcephei]

@mjsax I've moved the class as you suggested and also rebased on current trunk.
