Periodic logging for additional metrics

[rymnc]

Should resolve #984

• chore: enable metrics logging by default
• feat(logging): add additional logging metrics, change period to 30 seconds

We now log the following fields:

• Total connections initiated (peer count) since last log
• Total Messages
• Total SWAP peers
• Total FILTER peers
• Total errors since last log
• Total subscribed topics

Should the docs mention which fields refer to values over the last reporting period vs since the node setup?

[rymnc]

Additionally, should we log out the metrics using metrics/chronicles_support, as mentioned here, instead of casting them to float64's ourselves?

A little nitpicking.

LGTM ✅

Tip: Rebase your branch on top of master instead of merging master into your branch to update it with the latest changes. It makes the PRs cleaner.

Good job! Congratulations on your first PR. 🥳 I have added some minor comments on log completion, consistency, etc. If possible, could you add an example log output to this PR to get an idea of how it will look when printed to stdout?

[rymnc]

Thanks for your comments, I'll get those changes in tomorrow
