Upgrade to npm 5.8.0

[MartinX3]

Are there any plans to upgrade to npm 5.8.0?

I use the nodejs version v9.10.0 on Linux Ubuntu Mate 17.10 x64 and still have npm v 5.6.0

You know you can install npm seperately

See #19560

@richardlau and @Trott
Thank you very much.
I thought #19560 was about to add NPM v5.8.0 only to Node 8 LTS, while I'm using Node 9
