Reverts #7448 to unhide prune history option. I've been running this on mainnet for a while and it's seems pretty stable with no noticable impact on performance. The feature is already widely used even though it was hidden so might as well show it in our docs.

Metrics from my node

I did a few tweaks to how we query keys but nothing really improved the fetch keys duration.

Caveat still remains that it's quite slow on first startup if the previous db is large but that's a one time operation.

Closes #7556

Summary of Changes

Hello @nflaig, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request re-enables and documents the --chain.pruneHistory option, making it accessible to users after successful long-term testing on mainnet. The change reflects confidence in the feature's stability and utility for validators aiming to minimize data storage. Additionally, it refines associated metrics for improved monitoring of pruning performance.

Highlights

  • Feature Visibility: The --chain.pruneHistory option, which allows validators to prune historical blocks and states, has been unhidden. This reverts a previous change that concealed the option.
  • Documentation Update: The 'Pruning history' section in the data-retention.md documentation has been made visible, providing users with information on how to utilize the --chain.pruneHistory flag.
  • Metrics Granularity: The lodestar_prune_history_fetch_keys_time_seconds metric now includes more granular buckets (0.3s, 0.5s) to provide better insight into the performance of key fetching during history pruning.

Code Review

This pull request unhides the --chain.pruneHistory option, making it visible in the CLI and documentation. The changes are straightforward and achieve the intended goal. I've added one suggestion to improve the documentation by including a caveat about the initial performance of this feature, as mentioned in the PR description. This will help manage user expectations.

Code Review

This pull request successfully unhides the --chain.pruneHistory option, making it officially supported. The accompanying documentation update is clear and helpfully includes a warning about the initial pruning time on large databases. The adjustment to the histogram buckets for lodestar_prune_history_fetch_keys_time_seconds is a good improvement for metrics granularity. I've added one suggestion to also update the buckets for the pruneKeys metric for consistency, as it appears to have a similar performance profile.
