Job settings endpoint where settings for a job that apply to conjob can be configured

[ScottG489]

An example of this might be to configure a job to run on a schedule (although the feature isn't implemented yet). These would be settings for a job as they apply to conjob, not to the job run.

Some ideas:

• Set max number of concurrent runs (less than or equal to global setting)
• Set job to run on a schedule
• Set default timeout
• Set job to kick off another job (this idea should be thought through carefully)

Should the config and secrets endpoints be moved under this? (i.e. settings/secrets and settings/config)
