    Fixes `LP#1892210
    <https://bugs.launchpad.net/kolla-ansible/+bug/1892210>`__ where the number
    of open connections to Memcached from ``neutron-server`` would grow over
    time until reaching the maximum set by ``memcached_connection_limit`` (5000
    by default), at which point the Memcached instance would stop working.
Add workaround for keystonemiddleware/neutron memcached issue There is an issue where keystonemiddleware connections to memcached from neutron-server grow beyond configured values [1], eventually reaching the maximum number of connections accepted by memcached servers. Other services do not appear to be affected by this issue. A workaround is to use the advanced memcached pool. Despite its documentation claiming to only work with Python 2, it appears to work fine on Python 3.
