[Codebase]: Separation of Concerns with R Packages

[jimbrig]

Ideally we want to have better separation of concerns with minimal coupling between the various components of the GMH project (i.e. Entrata API Interactions, R Shiny Modules, Authentication Plumber API, Database Management, Data Pipeline Orchestration, etc.).

Could split the codebase into separate self-contained, independent yet cohesive R packages if deem necessary. My initial instincts would be to split out:

• GMH "DataHub" (Verse) Package (gmhdatahub)
• Leasing & Pre-Lease Logic
• Market Survey Logic
• Entrata API Wrapper Package (gmhentrata)
• Authentication API and R Wrappers (gmhauth) - Note: should merge noClocksAuthR and noClocksAuthPlumber and remove unused code while refreshing underlying code
