Swaziland was renamed to Eswatini in 2018. Time to update naming in Odoo.
We choose to make it in 16 as
* it is the newest stable, not much people are using it in production, aka
most people will have the updated name;
* there is no need to rename it for all production databases previously
as if used, it is easy to update its naming from Odoo directly;
Cheers !
