[SIEM][Detection Engine] Fixes skipped tests (elastic#71347)

## Summary

* elastic#69632
* Adds a retry loop in case of a network outage/issue which should increase the chances of success
* If there is still an issue after the 20th try, then it moves on and there is a high likelihood the tests will continue without issues.
* Adds console logging statements so we know if this flakiness happens again a bit more insight into why the network is behaving the way it is.
* Helps prevent the other tests from being skipped in the future due to bad networking issues. 

The errors that were coming back from the failed tests are in the `afterEach` and look to be network related or another test interfering:

```ts
1) detection engine api security and spaces enabled
01:59:54         find_statuses
01:59:54           "after each" hook for "should return a single rule status when a single rule is loaded from a find status with defaults added":
01:59:54       ResponseError: Response Error

01:59:54        at process._tickCallback (internal/process/next_tick.js:63:19)
01:59:54  
01:59:54               └- ✖ fail: "detection engine api security and spaces enabled find_statuses "after each" hook for "should return a single rule status when a single rule is loaded from a find status with defaults added""
01:59:54               │
01:59:54               └-> "after all" hook
01:59:54             └-> "after all" hook
01:59:54         │
01:59:54         │42 passing (2.0m)
01:59:54         │1 failing
```

So this should fix it to where the afterEach calls try up to 20 times before giving up and then on giving up they move on with the hope a different test doesn't fail.
