Code Issues Proposed changes

Database connection pooling improvements 

- Implemented new variable ``connection_recycle_time`` responsible for SQLAlchemy's connection recycling
- Set new default values for db pooling variables which are inherited from the global ones.

Depends-On: https://review.opendev.org/c/openstack/openstack-ansible/+/819424
