We are encountering an issue where the emulator process (Azurite/MinIO) starts and the TCP port opens but the emulator is in a bad state and the initial requests fail persistently with IO errors causing the tests that depend on them to fail spuriously. All instances that we have observed have succeeded upon retry with a fresh emulator process so this PR adds the process restart retry logic to CloudTest itself to prevent flakiness downstream.
