Bug Description

This is a continuation of https://bugs.launchpad.net/tripleo/+bug/1649252 because the original problem there has been fixed, but now we're hitting a different one.

The relevant bit is Sagi's comment:

"""
There is no enough space on our undercloud (nodepool images), which fails ironic deployments:

It's entirely possible we just need to increase the size of our undercloud vms. Note that this is somewhat problematic because the undercloud vms are a standard infra flavor, and changing the disk size would give us another snowflake trait.
