Use tempest.lib code in tempest
Now that tempest_lib code is copied back into tempest, stop using
tempest_lib in tempest, and start using the copied code.
Remove the dependency to tempest_lib from requirements, and drop
the script to use tempest_lib in tempest. Add os-testr to the
test-requirements.
Partially implements bp tempest-lib-reintegration
