fix(tests): Fix retries for the non-deterministic test suite (#5307) 
## Issue being fixed or feature implemented
the problem with retries implemented in #4793 is that they don't really
do anything besides fetching results of a failed job multiple times 🙈

## What was done?
partially reverted changes done in #4793, implemented actual job
restart. dropped `--sleep` and `--retries` and added `--attempts`
instead.

## How Has This Been Tested?
Pick any test, add some randomly failing expression somewhere and run it
with some high number of retries.

For example:
```diff
diff --git a/test/functional/feature_dip0020_activation.py b/test/functional/feature_dip0020_activation.py
index 471e4fdc66..b56a954b78 100755
--- a/test/functional/feature_dip0020_activation.py
+++ b/test/functional/feature_dip0020_activation.py
@@ -69,6 +69,7 @@ class DIP0020ActivationTest(BitcoinTestFramework):
         # Should be spendable now
         tx0id = self.node.sendrawtransaction(tx0_hex)
         assert tx0id in set(self.node.getrawmempool())
+        assert int(tx0id[0], 16) < 4
 
 
 if __name__ == '__main__':
```

On develop:
```
./test/functional/test_runner.py feature_dip0020_activation.py --retries=100 --sleep=0
```
if this fails on the first run, it keeps "failing" (simply fetching the
same results actually) till the end.

With this patch:
```
./test/functional/test_runner.py feature_dip0020_activation.py --attempts=100
```
if this fails on the first run, it can actually succeed after a few
attempts now, unless you are extremely unlucky ofc 😄

Also, check [ci results in my repo

ci scripts

This directory contains scripts for each build step in each build stage.

Currently three stages lint, extended_lint and test are defined. Each stage has its own lifecycle, similar to the Travis CI lifecycle. Every script in here is named and numbered according to which stage and lifecycle step it belongs to.

Running a stage locally

Be aware that the tests will be built and run in-place, so please run at your own risk. If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.

The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory. While most of the actions are done inside a docker container, this is not possible for all. Thus, cache directories, such as the depends cache or ccache, are mounted as read-write into the docker container. While it should be fine to run the ci system locally on you development box, the ci scripts can generally be assumed to have received less review and testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci system in a virtual machine with a Linux operating system of your choice.

To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage requires docker to be installed. To install all requirements on Ubuntu, run

sudo apt install docker.io bash

To run the default test stage,

./ci/test_run_all.sh

To run the test stage with a specific configuration,

FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
