[jira] [Commented] (AURORA-1686) Add an http endpoint in the scheduler to provide visibility into the available tiers

Mehrdad Nurolahzade commented on AURORA-1686:
---------------------------------------------

This can be done in a similar fashion to how task statuses are implemented, that as, a short description of tier is displayed as a pop-up text when user hover mouse over the name of the tier.

We need to modify {{tiers.json}} and associated logic so that a new JSON property like {{description}} is recorded for tiers. For example:

{code:title=tiers.json}
{
  "default": "preemptible",
  "tiers":
  {
    "preferred":
    {
      "preemptible": false,
      "revocable": false,
      "description": "Preferred tasks ..."
    },
    "preemptible":
    {
      "preemptible": true,
      "revocable": false,
      "description": "Preemptible tasks ..."
    },
    "revocable":
    {
      "preemptible": true,
      "revocable": true,
      "description": "Revocable tasks ..."
    }
  }
}
{code}

> Provide a way for cluster-operators and users to view the available tiers and the individual tier configuration via the scheduler UI.
> This could be implemented as a new http resource under / (root path) in the scheduler UI.
