Upgrades a set of hbase-server and hbase-rsgroup tests to JUnit 5 (Jupiter), including parameterized test migrations and shared test helpers.

Changes:

• Migrated many tests from JUnit4 annotations/rules/categories to JUnit5 annotations, assertions, and tags.
• Reworked parameterized tests to use @HBaseParameterizedTestTemplate + @TestTemplate and JUnit5 TestInfo.
• Introduced AbstractTestRpcServer to consolidate common RPC server test behavior across multiple test classes.
