Tasks:

• Turn (exploratory) octave scripts into python for automatic plotting
• Find a better way to extract Prometheus graphs. By "better", I mean
  • a) less manual than Firefox snapshot feature
  • b) allowing for customizing things like labels, legend, axes setup, title
• Modify loadtime tool to sort the output of the experiments #799
• Update the e2e runner to be able to start and stop CometBFT testnet processes on non-local machines #55
• Update the e2e runner to disconnect a node from network in Digital Ocean testnet #58

DoD:

• No existing octave scripts no longer there (new, exploratory ones accepted)
• loadtime outputs sorted results
• There is an automatic process to extract Prometheus graphs
