We recently ran a large-block experiment on the testnet and plan to do a further experiment on mainnet.
Although the metrics recovered from lighthouse nodes were quite useful, I think we could do with greater resolution in the block delay metrics and get some specific values for each block (currently these can be lost to large exponential histogram buckets).
This PR increases the resolution of the block delay histogram buckets, but also introduces a new metric which records the last block delay. Depending on the polling resolution of the metric server, we can lose some block delay information, however it will always give us a specific value and we will not lose exact data based on poor resolution histogram buckets.
## Issue Addressed
No issue has been raised for these broken links.
## Proposed Changes
Update links with the new URLs for the same document.
## Additional Info
~The link for the [Lighthouse Development Updates](https://eepurl.com/dh9Lvb/) mailing list is also broken, but I can't find the correct link.~

## Issue Addressed
#3853
## Proposed Changes
Added `INFO` level logs for requesting and receiving the unsigned block.
## Additional Info
Logging for successfully publishing the signed block is already there. And seemingly there is a log for when "We realize we are going to produce a block" in the `start_update_service`: `info!(log, "Block production service started");
`. Is there anywhere else you'd like to see logging around this event?

## Proposed Changes
Decouple the stdout and logfile formats by adding the `--logfile-format` CLI flag.
This behaves identically to the existing `--log-format` flag, but instead will only affect the logs written to the logfile.
The `--log-format` flag will no longer have any effect on the contents of the logfile.
## Additional Info
This avoids being a breaking change by causing `logfile-format` to default to the value of `--log-format` if it is not provided.
This means that users who were previously relying on being able to use a JSON formatted logfile will be able to continue to use `--log-format JSON`.
Users who want to use JSON on stdout and default logs in the logfile, will need to pass the following flags: `--log-format JSON --logfile-format DEFAULT`
Issue #3112
Add `Filter::recover` to the GET chain to handle rejections specifically as 404 NOT FOUND
Making a request to `http://localhost:5052/not_real` now returns the following:
```
{
"code": 404,
"message": "NOT_FOUND",
"stacktraces": []
}
```
