generate network-device configurations

[smnmtzgr]

I replaced Ansible+Jinja2 as templating-solution to generate the intended configuration of our network-devices. Since the data structure gets very big now (at the end I have a file with about 280.000 lines) Ansible+Jinja2 get very slow. It took 20 minutes to generate the final file out of the input data+template. Thats why I was looking at CUE. My goal was to make this a lot faster and to replace Jinja2 completely with CUE.

After learning CUE and reading the documentations I got my transform.cue files to a working state. I still need to refactor them and make them more efficient to prevent repeating-code... but my template-generating time to build the over 280.000 lines long file already dramatically reduced from 1418.42s (Ansible + Jinja2-Templating) to 35s (CUE).

This is great @smnmtzgr! From 23 mins, 30 secs to only 35 seconds!

How often do you have to run template generation from this large config file?
