[Container-tools] Community Node.js Builder Images

[Ben Breard]

Thanks Brian,

First, Fedora & CentOS versions of this container are in the works and will
be available soon, if they're not already. Sorry, I don't track the
community side as closely as I'd like to these days due to bandwidth.

I found similar results rebuilding our nodejs containers using rhel7-atomic
as the base; however, these benefits aren't shared by a lot of our
containers. This is largely due to how our package maintainers declare
dependencies. Installing packages like httpd & mariadb, don't typically
need systemd running in the container, yet they're deps so systemd gets
pulled in whether we want it or not.

I looked at mysql & mariadb images and they shrink by about ~10 MB. I was
really hoping that the base s2i image would shrink considerably, but
unfortunately with all the deps we pull in, that's just not the case. I'm
going to look at some of the xPaaS images and see if there's a tangible
benefit there as well.

...but I agree node is a great candidate here, so is java & golang.
