Report tests to datadog from Job that executed them

Previously, each test run was associated with the Job
that uploaded them.
This makes it harder to understand under which configuration
a specific test failed.
Now we immediately upload test results from the
respective job.

This increases feedback time slightly by up to 1 minute
(the slowest single upload time).
I'd say this is an acceptable tradeoff given our
current CI times.

This reduces the time until a "Retry failed jobs"
is avaiable since we no longer need to pass the test
results between jobs.
