We in openstack-infra have not see this issue, mostly because we have migrated
away from Jenkins. What i would suggest, is updating python-jenkins to do what
you have suggested, switch from GET to POST and see if nodepool becomes happy.

I did take a quick look into review.openstack.org, but didn't see any existing
patches around this issue.
