TST_{SETUP,CALLER}_CALLER takes setup from the test.
It's IMHO cleaner way allowing tests to set their setup/cleanup functions and
not care that there is also some library setup/cleanup (kind of encapsulation).
We already used this for setup, I wanted to have a same approach for both setup
and cleanup. Sure I can instead add ima_setup/ima_cleanup into tests' setup/cleanup
functions, but both solutions are working and I consider encapsulation as a benefit.
The only problematic thing would be if some test needed to run it's custom
cleanup *before* library one while other tests *after*. But that's not a case here.
We also use this approach in tst_net.sh [1].
