Support TimeoutInMinutes parameter in CloudConfig

Right now in our live test pipeline configs we only support a global `TimeoutInMinutes` parameter, which extends the maximum possible runtime for a pipeline test. In sovereign cloud testing, often the service API operations are much slower, so we need to bump the timeout parameter. However, it is not ideal to bump the parameter for the public cloud since we expect tests to be much faster and do not want to wait for timing out/failing test results.

This issue should track updating this for all languages with sovereign cloud testing and cloud config support (net, java, python, js, c++, go).

Start with JS first since that's where the ask came from: https://github.com/Azure/azure-sdk-for-js/issues/21153#issuecomment-1101718820
