Add health indicator

[pzamzow]

When using the module in a productive environment, e.g. hosted in Kubernetes, it is very important to have a health check for your application. This health check should include the connection to dependent services (e.g. messaging server). Therefore it would be very helpful, if the module would provide a health check functionality, which could be integrated into nestjs/terminus.

Hi @pzamzow ,

Sorry for the late answer.

Very good idea, would you mind creating a PR for it?
