poc(beacon): configurable templates for beacon api

[harmbrugge]

#4533

What are the main changes you did

• Added a templates table in the system schema
• Added a templates tab in "Admin > Templates" to configure the templates
• Load default templates in db from templates at classpath.
• Beacon api looks for a custom template or else picks the default template.

How to test

• Go to https://preview-emx2-pr-4536.dev.molgenis.org/apps/central/#/
• Log in as admin
• Create a schema with the BEACON template or other beacon compatible schema
• Go to Admin > Templates
• Change a template and link it to the created schema e.g. the individuals template
• go to: https://preview-emx2-pr-4536.dev.molgenis.org//api/beacon/individuals
• The response should now include the changes from the template

Checklist

• updated docs in case of new feature
• added/updated tests
• added/updated testplan to include a test for this fix, including ref to bug using # notation

maybe move into existing app ( central , admin, ui, ..) to avoid copy pasting app setup, build config, components, dependancies,..
