Trails help prevent performance issues

[jaumard]

Issue Description

A nice addition to Trails could be something like this:

debug: trails event: trails:start
debug: trails event: trailpack:repl:validated (2s)
debug: trails event: trailpack:pluginsManager:validated (20s)
debug: trails event: trailpack:chatbot:validated (1s)
debug: trails event: trailpack:cache:validated (0.2s)

Like this we can find easily what is causing performance issues (here pluginsManager:validated).
It should be activated only in debug mode but if trails(or maybe a trailpack) can provide something like this it would be nice.

Environment

• node version: all
• trails version: all
• operating system: all
