Hot

Added a `-s`, `--sleep` option to allow user to set the amount of time in seconds to wait before checking for updates. For things like nightly builds, it's probably worth setting the sleep to something higher than the default 15 seconds to reduce load on the Heat service. Example usage for something like a nightly build:


hot test --sleep 120


This example will change the sleep time to only check the status of a build every 120 seconds.

Adds a feature that will allow a user to specify which tests to run. Use case is for when a user would like to run an individual, or subset of tests specified in their `tests.yaml` file.

The `script` test type allows for users to run tests on environments and resources.

Allow user to pass `--keep-failed` to `hot test` to keep a failed stack up on failure for further investigation.
