Disable Sql*ReliabilityTests on Azure

[mdaigle]

Description

These tests are flaky, primarily on ubuntu22. Disabling for azure avoids running the tests on ubuntu22, but maintains some test coverage via local server test stages.

Issues

#3821

[Copilot]

Pull request overview

This PR addresses flaky test issues on Azure environments (primarily ubuntu22) by restricting SqlConnectionReliabilityTest test methods to run only on non-Azure SQL Server instances. The tests rely on specific error codes (like error 4060) that are not reliably returned when using Azure SQL or AAD authentication. This approach maintains test coverage via local server test stages while avoiding flaky failures on Azure.

• Added IsNotAzureServer conditional attribute to six test methods
• Added explanatory comments referencing issue #3821
• One test (CreateDatabaseWhileTryingToConnect) already had the restriction in place

Looks like the SqlCommandReliabilityTest.RetryExecuteAsyncCancel test is still running in Ubuntu22_Azure_Sql configuration where it failed in both pipelines.
