config/pod1.yaml: Typo fixes, add 3 new nodes

In order to be able to check the PDF template against the current
installer adapters, we need to fill in all 5 nodes info.

While at it, perform some cleanup:
- s/remoteparas/remote_paramsg/ (installers use this directly ...);
- s/remote_mangement/remote_management/g;
- s/pod owner/pod_owner/;
- minor typo fixes;
- fixed one IP overlap between 2 existing nodes;

NOTE: Data for the 3 new nodes is bogus (random MACs, addresses).
