Test integration of an aztec l2 full-node

Problem to be solved

I wanted to see how much work it was to support an aztec full-node in the stack. Here's what I found:

• Their charts aren't packaged into a chart museum. So i had to fork them locally. Could be added to the obol helm chart repo, or maybe they could add a chart museum to their CI and publish them to github pages.
• I had to throw out this volume mount, it wasn't found. https://github.com/AztecProtocol/aztec-packages/blob/next/spartan/aztec-node/templates/statefulset.yaml#L151
• I had to figure out they ran on sepolia. That took longer than I admit.
• I had to add sepolia as a supported network on eRPC. For now trusting publicnode.com, without any light-client safety from helios.
  • actually eRPC wasn't working, I had to go direct to public-node.com, something to debug.
• I had to expose a host port for them. Maybe networkMode: host might have worked instead, but i didn't want to test it when i figured manually setting a port and supplying --host to obolup would work.
• I had to create a values file for the chart to override the needed pieces. Maybe an aztec hosted example would suffice if there was a solution for the nodePort thing.
