Catalog traefik binary

[witchcraze]

What would you like to be added:

An additional file classifier which finds traefik binary.

Why is this needed:

traefik is widely used.

pullCount : 1B+
starCount : 2.8K+
from https://hub.docker.com/_/traefik

traefik will be installed without a package manger in container env with official image.
We want to be able to catalog this.
