Master / slave terminology in django framework replaced with leader / follower for political correctness reasons

Throughout the project, including code, the generally accepted terms master / slave have been changed to leader / follower.
Here is how the author of the fcurella patch substantiated this :
The documentation and some tests contain links to the master / slave database configuration.
Although this terminology has been used for quite some time, these terms may carry a racist background for users.
This patch replaces all uses of master and slave with leader and follower.
Apparently Mizulin is a rather international term, and not just Russian.
