Complete implementation of destroy which goes through each stage

[costrouc]

Closes #1092

This is a tricky implementation since we have multiple stages. Several of these stages require credentials kubernetes and keycloak to work. Destroy now works like the following

stages: 01, 02, 03, ... 08

for stage in stages:
    stage_ouputs = terraform output (stage)

for stage in reversed(stages):
    terraform destroy 

kubernetes and keycloak context are applied correctly along with all needed variables
