Set the health of this service. This is useful for services which have periods where they are unavailable. Typically this is directly after starting, but sometimes also a period where they gather data.

For a service with a delayed startup, the pattern is as follows:

		func main() {
		 server.SetHealth(common.Health_STARTING)
	         go do_initialisation()
		}
	        func do_initialisation() {
	            doing_slow_things() // ...
	            server.SetHealth(common.Health_READY)
	        }
