[disk-buffering] `StorageConfiguration.Builder.setTemporaryFileProvider()` exposes internal class

[bencehornak]

The public StorageConfiguration.Builder.setTemporaryFileProvider class requires an instance of the TemporaryFileProvider class, which is situated in the io.opentelemetry.contrib.disk.buffering.**internal**.files package:

opentelemetry-java-contrib/disk-buffering/src/main/java/io/opentelemetry/contrib/disk/buffering/StorageConfiguration.java

Line 84 in be32409

public abstract Builder setTemporaryFileProvider(TemporaryFileProvider value);

As a result, the users of the library need to import the internal class if they wish to provide a custom implementation.

My suggestion is to move the TemporaryFileProvider class to the io.opentelemetry.contrib.disk.buffering package to explicitly mark it as public API.

Thank you for letting us know, this was a miss from our side. I'll create a PR to move it to a public package.
