[TECHDEBT][Persistence] Fix Persistence Module TODOs - Lowercase Functions #149

[jessicadaugherty]

Objective

A general cleanup issue is needed to tackle TODO's and ensure the persistence module is usable/readable by making functions lowercase as part of #172.

Origin Document

Should follow issue-#128, issue-#105, issue-#147 and issue-#148 the persistence module is messier and more difficult to understand than the developers would want for organic external contribution.

Goals / Deliverables

• Make functions lower case (i.e. not exposed outside the specific package) if it does not need to be. This is a best-effort task.

General issue checklist

• Update the appropriate CHANGELOG
• Update the README
• If applicable, update the source code tree explanation
• If applicable, add or update a state, sequence or flowchart diagram using mermaid
• Update any relevant global documentation & references
• Document small issues / TODOs along the way

A good starting point is to use regex find inside the persistence module for func (.*) [A-Z] and comparing it to the interface in modules/persistence_module.go to determine what MUST be exposed.
