Create a new healthcheck endpoint

[froi]

We are currently using the root of the API (/api) as an informative and healthcheck endpoint for our API. This endpoint can only be accessed using an API key. We want to create a separate healthcheck endpoint and leave the /api endpoint for informative uses.

Describe the solution you'd like

• Create a /healthcheck endpoint with API status information
• Modify the /api endpoint to display only informative data about the API. Eg. where are the developer docs, where are the swagger docs, the running API version. etc.

api endpoint no longer implemented in current version (v2.6.1).
