Fixes for info votes

Fixes for info votes

gerrit trigger is not working in opnfv.
we had this happen to some of the read the docs jobs...
An updgrade of gerrit is planned to hopefully resolve this.

Not sure were to test to approval category stuff.
That said I think the mistake is that the value is an int.

            approval-category: 'WHATEVER'
            approval-value: 2

I dont actually want the script to exit on first error, need to output
the vote verdict.

not sure why I thought that JENKINS_SSH_CREDENTIAL
was the correct var for the ssh user.
switched to $USER
