Added route tag

[tburschka]

This pr will add support for the "@route" tag. This could be useful in environments, where the log is parsed and grouped by the route (e.g. Grafana).

Hi! Thanks for the contribution.

I wondering if the logRoute method has the same data of logPath, could you please create a test or improve them for this case?

[faabiosr]

Looks great!
Just one small adjustment, inside of each logger will you see the docs of adding fields, could you please update this part by adding the route?

And the last one, I promise 😊, just squash all commits please.

Does github not having a squash featurue during merge by the owner?

[tburschka]

I'm a little bit confused, hope i did the squash right, if not i can create a new mr with a single commit

[faabiosr]

Still showing 5 commits, and unfortunately this repo does not have the squash feature enabled.
