Should/Could we include a health endpoint in the Azure Functions project templates?

[stijnmoreels]

What is your question/concern?
Could we include an endpoint that has the health status, like we did for the Web API but in the context of Azure Functions?
Seems like this is something that will also be added a lot when people create Azure Functions?

Will be done as part of #378
