kubernetes generate config on-the-fly from catladder-config and template on deploy

[macrozone]

goal: there should be no config other than the catladder-config.

It's possible to pipe-in configs into kubectl apply, so at least in deployment, it should be possible to generate the yaml on-the-fly by variables from catladder-config and a template (tbd.).

the whole kubernetes is quite complicated, but it has not much "moving parts":

• app-name
• namespace
• current tag for docker image
• whether or not it needs a worker-process
• number of pods / workers
• db-config (if so)
• env-variables (from pass)
