Schedules: A new way to setup cron based monitoring rules in Dr. Droid

Use-case: Some of our users want to run certain SOPs frequently. A lot of times, they don't want to get notified every time, but only when trouble mongers. Sample examples of this:

• Repetitive steps, at a fixed frequency
• Periodic Assessment/Operations

Here's what a schedule setup looks like:

Sample use-cases could be:

1. "Execute the SOP for Payment Service SLO Review" everyday at 11am and notify me only when it fails or identifies an issue with the SLO. Also send a weekly
   1. Prompt: Execute the SOP for Payment Service SLO Review
   2. Cron: everyday at 11am
   3. Notification Policy: notify me only when it fails or identifies an issue with the Payment Service SLO
   4. Aggregated Summary: NA
2. "Review the dashboards in Grafana related to Kubernetes Cluster Memory" every hour and notify me only when it fails or identifies an issue with the Cluster memory. Also send a daily summary explaining the scans from yesterday.
   1. Prompt: Review the dashboards in Grafana related to Kubernetes Cluster Memory
   2. Cron: every hour
   3. Notification Policy: notify me only when it fails or identifies an issue with the Cluster Memory.
   4. Aggregated Summary: Generate summary report every day
