This allows to write pytests using the new stateful objects.
To add an object use the symbol '%', followed by the name, type and
specifications (currently used in quota):
%cnt1 type counter;ok # Adds the counter cnt1 to all tables
%qt1 type quota over 25 mbytes;ok # Adds the quota qt1 to all tables
