[Core][Storage] Run pre-validation test cases for storage test set to ensure server end data readiness.

[katmsft]

After the deployment is done and before the ctest gets triggered, there needs to be an additional phase to validate that the service properties can be correctly got and role assignment has taken effect.

[katmsft]

This can be achieved by a special regex for gtest command. However this needs to be supported by engsys.

@katmsft -- What regex needs to be supplied to the command? I can help wire this up.

Storage tests has been working properly for a long time. I guess this feature request is not needed anymore.
