(#469) Assign correct environment to node groups

bastelfreak · bastelfreak · commit ec84e0c53589 · 2024-08-23T14:28:59.000+02:00
This checks if a user configured a environment in pe.conf. If that's the case, it will be used for the PEADM-specific node groups. Otherwise we fall back to production. This fixes a timing issue discovered in #469. In situations where the PE infra isn't running in production, we cannot assume that a production environment exists. And a node group can only reference classes from the environment the node group belongs to.
