slaprunner/test: Extend and include tests to increase coverage
This is partially WIP but I let @jerome, @Nicolas and @tomo to review it.
Thie WIP is resilient tests included on it, it may cause the test runs for several hours.
My current idea is release all except resilient one, them use the Test case as a Library and recreate additional folders/softwares, which will run resilient tests.
It still required to see if we can optimise the compilation maximazing the use of shared.
