> Currently you can provide a job name to {{execute}} in the execution environment.  In an environment where many version of a job may be executing, such as a development or test environment, identifying which running job is of a specific version via the UI can be difficult unless the version is embedded into the job name given the {{execute}}.  But the job name is uses for other purposes, such as for namespacing metrics.  Thus, it is not ideal to modify the job name, as that could require modifying metric dashboards and monitors each time versions change.
> I propose a new method be added to the execution environment, {{setDescription}}, that would allow a user to pass in an arbitrary description that would be displayed in the dashboard, allowing users to distinguish jobs.
