[User research] Look at custom ConfigLoader implementations

[merelcht]

Description

We need to know what users put in custom AbstractConfigLoader, ConfigLoader and TemplatedConfigLoader implementations to find out whether changes to how config is loaded currently (with lists and glob patterns) would break those custom versions.

Research method

Interviews with users where they can show their custom implementations and talk through why/how they wrote it that way.

Outcomes

• Summary of what users implement in custom ConfigLoaders
• Insight into the impact that changes to the AbstractConfigLoader, ConfigLoader and TemplatedConfigLoader would have on custom implementations.

Subtasks

• Prepare ConfigLoader research questions + setup
• Schedule user interviews
• Tag user interviews
• Extract insights from configuration user interviews #1847
