Support Recording and Live Test Version Configurations in Testing

[alzimmermsft]

Add the ability to configure which service version test recording and live testing should use. These configurations will allow for scenarios where a service is previewing a new version behind a gate or isn't deployable through ARM to allow for tests to be recorded against the restricted environment but then allow for live testing to use a generally available environment. In addition to this, tests should be allowed to list which service versions they can be ran with, for cases when a test is only runnable in a version not supported by the configured live test version it will use the recorded service version and recorded test to perform testing in live testing.
