Fixes: #731

Description of the change:

Adds logic for automatic retry when an automated rule is activated but fails. This can happen because the discovered target application is not yet actually ready to accept requests, or because of some network hiccup, etc. Previously if an automated rule activation failed then Cryostat would never retry and the rule would not take effect on the target, until some other event caused a reactivation (rule disable/reenable, stored credentials added, target modified, target lost/found).

Motivation for the change:

Increases reliability of automated rules.

How to manually test:

  1. Deploy on k8s, ex. using Helm chart
  2. Deploy sample application. I used the Operator's make sample_app
  3. Create an Automated Rule that matches the sample application(s)
  4. Use various oc rollout restart deployment quarkus-test, oc scale deployment quarkus-test --replicas=n commands to cause targets to appear and disappear. Verify that automated rules consistently activate against these targets. There may be a slight delay in activation at times due to the retry/backoff behaviour.
