Docker-nginx: Nginx Mainline is lower version than stable (need 1.17)

[ducttapecoder-vt]

I know 1.17 was just released yesterday (so I don't blame that it's not up yet) but I see that the current mainline image is still 1.15.12 while stable is now 1.16. Shouldn't the mainline package always be at least the same version or higher as stable?

Also, has the null root password issue been fixed for alpine builds?

No, stable/mainline reflect actual nginx versions, and once a year (when the version bump comes) stable can be higher.

That being said, I do need to update the mainline to 1.17.0 anyway.
