[bug]: Performance regression in v0.33.1

[sodul]

Description of the bug

kapicorp/kapitan:0.33.1 is significantly slower than 0.33.0 when compiling.

Steps to reproduce

> docker run --rm --user=0 -v "$(pwd)/kapitan:/src" 'kapicorp/kapitan:0.33.1' compile

This completes in 6m while it takes 30s or less with v0.33.0.

### What happened?

We upgraded to 0.33.1. Nothing else is different.
