See the many dozens of changes switching from MySQL-python to
PyMySQL as our upstream default:

    https://review.openstack.org/#/q/topic:pymysql-switch,n,z

This direction was decided at the Liberty summit in Vancouver, and
upstream DevStack-based jobs default to PyMySQL for more than a
couple months now (since https://review.openstack.org/191113
merged). This both solves some locking-related performance issues
and gets us closer to Python 3.x support.
