## What changes were proposed in this pull request? `StreamingReadSupport` is designed to be a `package` interface. Mockito seems to complain during `Maven` testing. This doesn't fail in `sbt` and IntelliJ. For mock-testing purpose, this PR makes it `public` interface and adds explicit comments like `public interface ReadSupport` ```scala EpochCoordinatorSuite: *** RUN ABORTED *** java.lang.IllegalAccessError: tried to access class org.apache.spark.sql.sources.v2.reader.streaming.StreamingReadSupport from class org.apache.spark.sql.sources.v2.reader.streaming.ContinuousReadSupport$MockitoMock$58628338 at org.apache.spark.sql.sources.v2.reader.streaming.ContinuousReadSupport$MockitoMock$58628338.<clinit>(Unknown Source) at sun.reflect.GeneratedSerializationConstructorAccessor632.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.objenesis.instantiator.sun.SunReflectionFactoryInstantiator.newInstance(SunReflectionFactoryInstantiator.java:48) at org.objenesis.ObjenesisBase.newInstance(ObjenesisBase.java:73) at org.mockito.internal.creation.instance.ObjenesisInstantiator.newInstance(ObjenesisInstantiator.java:19) at org.mockito.internal.creation.bytebuddy.SubclassByteBuddyMockMaker.createMock(SubclassByteBuddyMockMaker.java:47) at org.mockito.internal.creation.bytebuddy.ByteBuddyMockMaker.createMock(ByteBuddyMockMaker.java:25) at org.mockito.internal.util.MockUtil.createMock(MockUtil.java:35) at org.mockito.internal.MockitoCore.mock(MockitoCore.java:69) ``` ## How was this patch tested?
