Add Possibility to Change Scanner and Hook Images

To make it possible to change the docker images for scanners and hooks
via values.xml I updated the following charts:
- kube-hunter
- ncrack
- nikto
- nmap
- test-scan

This is necessary for these charts because we do not use the official
images for these scanners/hooks and cannot rely on their image tags
