Add panw.panos.endreason field (elastic#18705)

PANW firewalls expone why a session is ended (endreason). Currenlty it's not tracked. End reason is important to track down why a specific session is ended (timeout, rst from client/server...). This adds panw.panos.endreason. Co-authored-by: Andrea Dainese <[email protected]> Co-authored-by: Adrian Serrano <[email protected]> (cherry picked from commit 6c0c3bf)
