fixes #2239 API v2 CRUD for locations and organizations and added nested loc/org

Fix home mapping in API v2

Home controller is in v1, mapping all the routes from scope for v1
except the final fallback, that needs to go to the end of routes file.

Oterwise status is not working for V2.

v2 api for configuration_templates and template_combinations

added API v2 placeholders.

fixes #1890 api host status

fixes #2037 remove catchall routes

this blocks any plugin/engine from adding additional routes

host routes api changes squashed

added template_kinds controller to api

set apiadmin user in headers before api controller tests

This commit adds most of the functionality required for API v1

The overall goal was to extract the existing JSON response
overall controllers, and to move them to a seperate name space.

• documentation was added to all requests (available under /apidoc)...
