Provide possibility to mark false positives inside report view

Story

Inside report view, when having a false positive finding as a developer I want to mark the false positive inside the ui and plugin shall send the information to server side.

Solution

• context menu entry in report view table row "mark as false positive" (double click)
• marked positive rows shall be have "false-positives:true" inside model and be shown in table as false-positive
• add toolbar button to filter false positives on/off
• provide button "sync with sechub server" - when having a connection to a sechub instance fetch false positive list and mark all entries from report being mentioned as false-positive in meta model so shown correctly inside view. This is interesting when an already partly reviewed/&handled report is loaded again in report view and developers want to see only non "true-positives"
