Implement a imperative subsequent scan Hook

[rfelber]

Is your feature request related to a problem? Please describe.
As a security test i would like to combine the different security scanners integrated in the secureCodeBox. Therefore it would be helpful to be able to use the parsed scan results of each scanner and decide if a subsequent scan is possible.

Describe the solution you'd like
For example if NMAP identifies open HTTPS or SSL ports it would be nice if a hook will catch them up and start a corresponding SSlyze scan. The subsequent scans should be referenced in the original scan to implement a object hierarchie of scan jobs. The deletion of the parent scan object will also delete all subsequent scans.
