OCP 4.7 upgrade tests failing to install AMQ Online 1.6 (0/6 nodes are available: 3 Insufficient memory)

We are seeing the upgrade tests failing on 4.7 on the install of AMQ Online 1.6 (i.e. before the upgrade to the new code has taken place). The brokers are failing to become ready due to a resource issue.
