###Gitlab: controllo i commit recenti dei singoli progetti###

#Questo script passa in rassegna tutti i progetti esistenti sul gitlab aziendale e per ognuno verifica la presenza di commit recenti in una finestra di giorni specificata
#Poi invia le statistiche rilevate a zabbix per avere lo storico dei progetti con commit recenti
