[repository] move cnxset pool handling to a helper class
The class has responsability to handle connections pool operations in a single
public attribute 'cnxsets'.
On Repository _get_cnxset() and _free_cnxset() are replaced by cnxsets.get()
and cnxsets.release().
Drop multiple access to private attributes and methods from outside of Repository.
