    Add eventlet db_pool use for mysql
    
    This adds the use of eventlet's db_pool module so that we can make mysql
    calls without blocking the whole process.
    
    New config options are introduced:
    
    sql_dbpool_enable -- Enables the use of eventlet's db_pool
    sql_min_pool_size -- Set the minimum number of SQL connections
    
    The default for sql_dbpool_enable is False for now, so there is
    no forced behavior changes for those using mysql.
    
    Adds a new test module for our sqlalchemy code, testing this new option
    as much as is possible without requiring mysql server to be running.
