Open Stack

We had a release job failure during the processing of the tag event when 
1.3.0 was (successfully) pushed to openstack/monasca-grafana-datasource.

Tags on this repository trigger the release-openstack-javascript job, 
which failed during pre playbook when trying to run yarn --version with 
the following error:

/usr/share/yarn/lib/cli.js:46100
   let {
       ^

SyntaxError: Unexpected token {
     at exports.runInThisContext (vm.js:53:16)

This prevented the job from running (likely resulting in nothing being 
uploaded to NPM? Not a JS job specialist), which in turn prevented 
announce-release job from announcing it.
