Ability to suspend/result jobs (OCP-425)

Problem: Scheduled jobs often fail due to an issue within app installation configuration or an issue in third-party service account. There is no way of suspending job execution for an installation until the problem gets solved
Solution: Add the ability to temporarily suspend scheduled job execution. This should be available per installation and both via manual intervention (OCP CLI) and a programmatic way inside the app
Impact: improves maintainability by removing noise
