Move OpenSRP Specific Changes to Fhir Gateway Plugins (custom repo)

[rehammuzzamil]

We need to move OpenSRP specific changes, including custom access checkers and custom endpoints (PractitionerDetails and LocationHierarchy), from the Gateway Server repository to a new dedicated repository. This issue will track the process of creating the new repository and transferring the relevant code.

Tasks

• Create a new repository for OpenSRP-specific changes.
• Set up the basic design and structure of the new repository.
• Move the code related to custom access checkers to the new repository.
• Move the code related to custom endpoints (PractitionerDetails and LocationHierarchy) to the new repository.
• Move Helm pieces related to deployment to the new repository.
• Create a exec module to bind gateway server dependencies (Plugins,Server) and the custom plugins together.

Additional Information:

• The Gateway Server repository currently contains the code related to these changes. Also move fixes done in this branch
• Make sure to update dependencies of the Gateway Server

Part of this issue is defined here.
