Added a new /v2/dry-run endpoint that allows for a synchronous dry run of a provided template. A supportsDryRun option has been added to createTemplateAction, which signals whether the action should be executed during dry runs. When enabled, the action context will have the new isDryRun property set to signal if the action is being executed during a dry run.
