Update Node 10 Alpine version

[mastersingh24]

Closes #998

Given Node 10 is the current LTS, it makes sense to move to Alpine 3.9. Node 11 images are already using 3.9 as well.

We can merge this after the upcoming security release, I think.

@SimenB we usually wait for a new Node version to avoid breaking builds etc.

[SimenB]

I know, but I don't think an OS upgrade should be bundled with a security update

[LaurentGoderre]

@SimenB yeah, I think it should be the one after the security update?

[PeterDaveHello]

I thought we will deliver that with a regular release?

[JCMais]

fyi we had some failed builds today because of this change, some native add-ons we use failed building and some apk dependencies were not found after upgrading to v10.15.3 because of the Alpine version bump.

We've had some issues with curl and SSL since this release.
Error was curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to <domain>
We've reverted back to 10.15.2-alpine which resolves it for now.

[LaurentGoderre]

Would that be because of the new version of Alpine?

[JCMais]

@LaurentGoderre most probably, yes
