"bay" and "baymodel" is not common term.
This patch renames "bay" to "cluster", and "baymodel" to
"cluster template" for 'Soft StringFreeze'[1] in Newton
Release Schedule[2].
[1] Soft StringFreeze: Aug 29 - Sep 02
[2] https://releases.openstack.org/newton/schedule.html
For translation work, this patch should focus to changing
strings to be translated and should be merged soon.
So, until "cluster" and "cluster template" is implemented
into Magnum API, Magnum-UI uses bay and baymodel of magnumclient.
