Code Issues Proposed changes

adding parameter to configure QueuePool in SQLAlchemy

Browse Source 
This patch introduces the parameter sqlalchemy_pool_size.
The parameter is used to configure the QueuePool, created
in configure_db(). At the moment the configuration of the
pool is only possible when using eventlet's db_pool for
MySQL (sql_dbpool_enable = True).
