A Vert.x Web handler on which you register health check procedure. It computes the outcome status (`UP` or `DOWN`)
. When the handler process a HTTP request, it computes the global outcome and build a HTTP response as follows:


204 - status is `UP` but no procedures installed (no payload)
200 - status is `UP`, the payload contains the result of the installed procedures
503 - status is `DOWN`, the payload contains the result of the installed procedures
500 - status is `DOWN`, the payload contains the result of the installed procedures, one of the
procedure has failed

 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**

Registers a health check procedure.
 The procedure is a taking a of Status as parameter. Procedures are asynchronous, and must complete or fail the given . If the future object is failed, the procedure outcome is considered as `DOWN`. If the future is completed without any object, the procedure outcome is considered as `UP`. If the future is completed with a (not-null) Status, the procedure outcome is the received status. 
 This method uses a 1s timeout. To configure the timeout use register.
