Upgrades

[jankeromnes]

There are new versions of Ruby and Node.js.

A word of caution: I didn't test this, so it might break things down the line.

Thanks for the contribution. Bumping node from 8 to 10 is not really a minor change.

[jankeromnes]

Ok you're right. It used to be a breaking change for Janitor, but Node 10 backwards compatibility seems to have improved lately because we were recently able to upgrade all our images without further changes or breakage.

But it should definitely be tested first. How can I do that?

Edit: I did this very quick change just in case it was useful. Please feel free to drop it for now if it's inconvenient. It could also be picked up later.

@akosyakov @AlexTugarev opinions?

[AlexTugarev]

Working on Theia requires node version 8. We'd need to create a custom image for Theia then, right?

[jankeromnes]

It's true that upgrading to node 10 used to break Theia's install, but this has now been fixed. Are there any other Theia / node 10 blockers that I'm not aware of? We should probably test this, and maybe take it upstream.

[AlexTugarev]

That's a good question. I've seen a lot of effort towards node 10 support, but I'm not sure how far this is.

I just did a quick test, and there is still something to to on the Theia side.

[AlexTugarev]

FYI there is a PR @kittaakos is working on to make Theia run with node 10.

[AlexTugarev]

+1 for bumping. We can handle it in Theia's .gitpod.yml

Isn't it that we have nvm there to let user use any version of Node.js he wants? In Theia (and other descending images) we can switch to some fixed version (currently 8.14.0, see #34), I'd also keep it there as a default in case someone wants to try Gitpod for opening the Theia project & build it, but we can preinstall Node 10 there too, so the user can switch fast. Am I missing something? (That's well possible)

[svenefftinge]

The question is what should be set by default. It makes sense to use the latest stable which is Node 10.

[orucky]

One note - I bumped Ruby independently in #34. I know there's also a bit newer version of Python (3.6.7), Node.js is current (in 8.* line), there's Clang 7 instead of 6.0 (I'm creating an issue for this one as it's a major version). The rest I haven't checked

Thanks all! This pull request is now superseded by #69 and #70.
