Cannot create `config.json` when running in OpenShift

[RobotSail]

I tried running IPFS Cluster in an OpenShift cluster and saw that the IPFSCluster cannot actually create the IPFS Cluster pods because the configure-ipfs container needs to write the generated settings to /config.json so that Kubo can read from a file with the same name.

I believe this is due to OpenShift's rather strict permission settings, but there must be a workaround here.

@RobotSail who does the container run as? I had to add a SA and update SCC related items. 4.12 is crazy awful in regards to running applications as well due to security so we will need to be aware of that too. I have notes if you want to link up
