Instrument Hanami using dry-monitor

[luismiramirez]

Timebox: 1 day (for research)

As mentioned by Peter Solnica in this toot, Hanami 2 uses dry-monitor by default. A gem like ActiveSupport::Notifications to monitor and instrument in Ruby.

The current integration is made by monkey patching Hanami::Action. Using dry-monitor would allow us to remove such monkey patch.

To do

- [ ] Add a listener for dry-monitor to our Ruby gem
- [ ] Test the data that is reported is useful, and report back if we are missing some data to Peter
- [ ] If we have enough data, ship the dry-monitor listener

• Add a hook for dry-monitor instrumentation
• Format rom-sql events that go through dry-monitor
• Update documentation

The dry-monitor rack instrumentation doesn't provide all the data we need.

Added a hook for dry-monitor similar to the one we have for ActiveSupport::Notifications and native support for rom-sql events.
