[lttng-dev] Stress tests added to ctf testsuite

We can run scripts, yeah. But, as far as I understand it, the ./run.sh 
scripts require passing a CTF_READER_BIN executable, which we don't have 
during the testing phase.

Another advantage of using parameterized tests is that it creates one 
JUnit test for every instance that is created at run-time (here, one per 
test trace to test). This way they show up individually in test reports 
[1]. And if one of them fails, at the end we know which one did, and not 
just "something failed in the script".

I see how the test files can be big, so generating *everything* may not 
be desirable. Could it be per test then? Or even part of the Python 
scripts themselves? (generate -> test -> clean, have a default array of 
sizes to generate, user can specify other sizes?)
