Change keyserver for nodejs key

[pnasrat]

Fixes #220 by using ubuntu keyserver due to lack of SNI support.

What's this PR do?

Changes the keyserver to import the package signing key to be ubuntu keyserver due to unsupported SNI on the nodesource servers.

Where should the reviewer start?

How should this be manually tested?

You can change vagrant.yml:

diff --git a/vagrant.yml b/vagrant.yml
index 080331d..3012a6f 100644
--- a/vagrant.yml
+++ b/vagrant.yml

 - name: Setup vagrant
   hosts: all
   roles:
-    - { role: dosomething.vagrant }
+    - { role: dosomething.nodejs }

Run vagrant destroy && vagrant up
