[PATCH 1/2] lib: Add a way to specify values for "quick" runs

[Damien Lespiau <damien.lespiau@intel.com>]

In some environments, we don't really want to loop 100000 times or
allocate 152352621 buffers because it makes the tests too long to run.

This adds a way to specify "quick" values to reduce the time taken by
certain tests.
