Allow to customize 'Move node info' + report details

[westram]

Quality of group transfer can neither be examined nor influenced.

Especially if topology differences between source- and target- are bigger,

• either many groups will be discarded (i.e. not transferred)
• or if transferred, there is no way to judge the quality (i.e. how well they fit)

Wanted improvements:

1. customize group-transfer-scoring
   • allow to set limits for
     • ingroup-ratio (min/max(?) percent of old members in new group)
     • outgroup-ratio (min(?)/max percent of non-group members in new group)
   • allow score weighting
     • introduce weight-factors (or non-linear weighting-functions?) for
       • ingroup- and outgroup-ratios
       • group-size
2. report transfer-quality
   • always report to log
   • optionally report to destination group name:
     • append fixed suffix to original group name
     • append custom information after suffix
     ⇒ search for specific groups is possible, while original name can be restored using ACI-rename
   • reported information:
     • score
     • ingroup- and outgroup-ratios
     • old + new groupsize
     • …
