TODO cleanup: osc-lib

osc-lib 1.3.0 is released, which contains these functions that still
need to be migrated all the way down to os-client-config.

Currently osc-lib 1.2.0 is in global-requirements so this can not be
merged yet, but is included here for testing and to be ready for when
g-r is unfrozen.
