- Provide a new reuqired parameter: [database]pooling_mode and use it during
SQLAlchemy engine initialisation.
- Update tests and configuration (including sample configuration).
- Adjust repository unit test to load config during setup.
- Pass an engine instance to repository constructors instead of connections.
Engine keeps a connection pool and we rely on it.
Provide 3 new configuration parameters in database section:
- max_connection_age --- number of seconds before an idle connection is
"recycled", i.e. replaced with a new one;
- pool_size --- number of simultaneous connections kept in the pool;
- max_overflow --- maximum number of simultaneous connections we could make to
the database.
Update sample config, including links to documentation.
