migrate CI test steps to containers

Today we use benni09 static agent to run test/gtest/valgrind steps which
is unscaleable since it can only run one pipeline at a time, causing
delays in builds that can be stuck waiting for hours

The idea is to move these steps to containers, allowing running them in
parallel as well as running multiple pipelines at the same time
(depending on the capacity of the k8s cluster)
