    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
    sql_max_pool_size -- Set the maximum number of SQL connections
    sql_idle_timeout -- Timeout before idle sql connections are reaped

    The default for sql_dbpool_enable is False for now, so there is
    no forced behavior changes for those using mysql. sql_min_pool_size
    is defaulted to 1 to match behavior if not using db_pool.

    Fixes bug 1086173
