Consecutive push option

[micellius]

Description

In the CI/CD flow it is hard to determine, whether the HTML5 application was already deployed or not. Also branching of commands is not desired and in some cases not possible. It would be beneficial to have an option for html5-push to create destination and app-host instance in case they are missing, but use existing otherwise.

Possible syntax may be

cf html5-push -d --consecutive

or

cf html5-push --managed

Use cases matrix

HTML5 application already deployed	Destination with same sap.cloud.service exists	Action
No	No	Create app-host service instance and destination
Yes	No	Redeploy application to existing app-host and create destination
No	Yes	Create app-host service instance and update destination with extra app-host-id
Yes	Yes	Redeploy application to existing app-host
