Description

There are some REST API responses that include keys with hyphens in them.  This results in the frontend having to use string-lookups to access those values and we lose the type information when doing that.

Example from /jobs/<jobid>/vertices/<vertex>/backpressure
export interface JobBackpressureInterface {
  status: string;
  'backpressure-level': string;
  'end-timestamp': number;
  subtasks: JobBackpressureSubtaskInterface[];
}
I would like to update all of these to use _ instead so we can maintain the type information we have in the web-runtime.

My suggestion to do this with out a version bump to the API is to just make an addition to all the enpoints that include the _ versions as well. Then after the web-runtime has completely switched over to using the new keys, you can deprecate and remove the old hypenated keys at your own pace.
