Reco QA - primary vertex

The current update address to issues:

• primary vertex finder procedure. The hard-codded cut on a primary vertex contributor track to have STS+TRD+ToF hits is exposed to the user. The results of various quality cuts on tracks are also marked. Final result is that the user can identify which track from the event DO contribute to the PV definition and make informed selection.
• monitoring the above mentioned features and track projection to user predefined z planes. Results from such procedure can be looked for here : https://indico.gsi.de/event/19534/contributions/82199/attachments/48667/70662/Qa_AB_240919.pdf
