It's very time consuming to test a change in step template.

To test a change, a user will need to:

1. Navigate to a project that use the step template
2. Update the deployment process
3. Create a new release
4. Cancel any failed deployment in the target environment
5. Deploy the release to the target environment

I propose adding a few optional parameter in the create release page to stream line the process.

1. Option to update all step templates
2. Option to automatically deploy to a target environment (this will also cancel any failed deployment that's waiting for user action).
