Change fake pull secret to a parsable value

[Reamer]

Due to various problems, we should change our fake pull secret example to a fake secret that is parsable.
Related issues:

• pullSecret issue in OKD4 docs #264
• error running chcon -R -t var_run_t /run/mco-machine-os-content/os-content-X: chcon: cannot access ...': No such file or directory\n: exit status 1" #576

Note: At the moment I have not tested an okd installation with this pull-secret, but I will do so this week.
EDIT: Done without problems.

Thank You!

I'm testing this now on a clean install... I will let you know how it goes! Installation has been a pain in recent weeks, fighting issues in latest oVirt and latest OKD... Last week, I stopped using my redhat pull secret and was relying on the dummy pull secret, and the installer would just sit dead in the water after provisioning the master VMs. Here's hoping this gets me further along like previously when I was using my redhat pull secret (but those installs would fail due to crashy ovirt engine)!

Glad I found this!

This new pull secret is working, and installation is proceeding as previously... I'm still seeing a very crashy engine VM. Engine was running idle for 5 hrs before I started installation, but is now crashing every 5 or 10 minutes as installation proceeds.

Thank you very much for your feedback. I installed two new clusters yesterday with the new fake pullsecrect without any problems.
