Refactor Logic Apps scripts with smaller function contents

**Is your feature request related to a problem? Please describe.**
Currently, the script files of the Logic Apps module contains a lot of functionality and complexity that makes reading and maintaining harder.

**Describe the solution you'd like**
We should look into providing additional functions within the script file to limit the code indentation (like: `if` > `if` > `foreach` > `if`).

**Additional context**
Follow-up of #413

Inspect the Logic Apps module's script files and review follow-up issue #413 to identify the functionality and nesting targeted by this refactor. Done means the existing behavior is preserved while the scripts use smaller functions and have less deeply nested logic.
