Confirmed here. CentOS 7.4.
Used to work fine in 7.3 (I’m left handed, main button is the right one to me).
Update to 7.4, main button became the left one, and gnome app does not change anything.
Changing mouse settings in control center doesn't work with the default evdev drivers, but is working fine with libinput driver.
To use libinput in X.Org the xorg-x11-drv-libinput driver is required.

As Jiri Koten instructed, I fixed this issue for a RHEL 7.4 user by installing the package:
It pulled in the dependency:
We did not have to reboot; we only had to log out of gnome & log back in. Although libinput does install udev rules.
Note that xorg-x11-drv-libinput provides:
If you have an xorg.conf or xorg.conf.d file with:
It might interefere.
> It pulled in the dependency:
That is correct behaviour, the xorg-x11-drv-libinput driver is a thin wrapper around libinput itself which does all the heavy lifting.

For your use-case the udev rules don't matter too much and after the next reboot (or plugging in of devices) they will apply.

The default ordering of the drivers in RHEL7 is that xorg-x11-drv-synaptics sorts higher than xorg-x11-drv-libinput and thus takes precedence. This was chosen because libinput's touchpad behaviour is somewhat different to synaptics' and we didn't want users to have to adjust to a new behaviour. This doesn't apply in the same extent the mouse/keyboard behaviour, so libinput sorts higher than xorg-x11-drv-evdev and thus overrides that driver if installed.
I am able to successfully adjust all mouse settings in GNOME 3.26 via GUI, including the important Left/Right primary button.
