this adds the possibility to define a check to see if a
cron callfunction needs to be executed before droping
elasticsearch triggers or calling the cron function

if the check function is not define then the cron
call function will be executed as before

to define the check function it has to have the name
of the cron callfunction and add a 'needs_to_run'
at the end

+ also making the successful login reset the logintries
to 0 for the user on the DB
