Disable cloud storage tests that would use @TempDir

[tmater]

Summary

Disables 5 view catalog tests for cloud storage providers (S3, ADLS, GCS) that use @TempDir. The ViewCatalogTests base class uses Paths.get() with the temp directory, which doesn't support cloud storage paths.

Follow-up to #2871.

Background

These tests inherit from Iceberg's ViewCatalogTests, which passes a @TempDir path to Paths.get(). Since Paths.get() only accepts local filesystem paths, it cannot handle cloud storage URIs. For example, when @TempDir provides /tmp/junit123, Paths.get() converts it to a URI like file:///tmp/junit123. But for cloud storage base paths like s3://bucket/path, it would incorrectly create s3:/bucket/path (single slash) instead of the valid s3://bucket/path format.

These tests are disabled to prevent false positives - they would pass by testing against local filesystem instead of actually validating cloud storage behavior.

Changes

Base test classes - Added @Disabled overrides for 5 tests:

• PolarisRestCatalogViewAdlsIntegrationTestBase.java
• PolarisRestCatalogViewGcsIntegrationTestBase.java
• PolarisRestCatalogViewS3IntegrationTestBase.java

Concrete test classes - Removed reflection workaround:

• RestCatalogViewAdlsIT.java
• RestCatalogViewGcsIT.java
• RestCatalogViewS3IT.java

Testing

Run cloud tests: ./gradlew cloudTest

Future Work

Will follow up with changes to Iceberg's ViewCatalogTests to avoid using Paths.get() with @TempDir. Once that's done, these tests can be re-enabled.

Good catch, @tmater !

I think disabling these tests for now is a reasonable approach.

However, in the log run, should we rather fix the tests to allow any (configurable) storage URIs?

Thank you for the quick review, @dimas-b and @snazy!

@dimas-b, I’ve already started experimenting with some changes. I don’t expect them to be too disruptive, but we’ll also need to bump our Iceberg version for that. I figured it’s better to disable these for now.

Yes, I'm sure an Iceberg change will be needed to make the test reusable in cloud environments.
