Add NCRACK cascadingRules for SSH Findings

[rseedorff]

Is your feature request related to a problem? Please describe.
As a Security Tester i would like to use the NCKRACK scanner in combination with NMAP to scan and tests a broader network range for weak authentication credentials.

The idea behind cascadingRules is described in the corresponding hook: https://github.com/secureCodeBox/secureCodeBox-v2/tree/master/hooks/declarative-subsequent-scans
And additionally in the ADR: https://github.com/secureCodeBox/secureCodeBox-v2/blob/master/docs/adr/adr_0003.adoc

Describe the solution you'd like
Therefore it would be great to use cascadingRule to start NCRACK automatically in the case if NMAP identifies SSH service in a network. Examples of already existing cascadingRules can be found in some of the other SCBv2 scanners, e.g. for ssh: https://github.com/secureCodeBox/secureCodeBox-v2/blob/master/scanners/ssh_scan/cascading-rules/ssh.yaml
