upcoming policy-related changes need a properly initialized
global oslo_config's CONF instance, which inspector's unit tests
currently lack.
As a side effect of implementing this, the 'dbsync' module was
changed to not register it's CLI options right on its import.
Also, setting default log levels was moved to a function which
is already registered as the one providing defaults to options
in oslo_config's entrypoints. Config sample is updated accordingly.
