Health check middleware

[MassimoC]

consider to use the health check middleware (ASPNET core 2.2)
https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/health-checks?view=aspnetcore-2.2

The idea of this is great but the implementation is not there yet imo.

For example it has no support for OpenAPI so it will not work with gateways

[MassimoC]

Actually in the first simple implementation I've explicitly excluded the Health check controller from the Open API generation ([ApiExplorerSettings(IgnoreApi = true)])
I thought was better to hide all those technical operations ... I don't have a clear opinion on this.

[tomkerkhove]

My vision on this is that it should be include to improve discovery. Restricted access is up to the gateway or app

But it's up to you

[MassimoC]

Add this as guidance on the maturity level2

I can pick this up if you want
