Implement periodic get-results on Bastion

[attekett]

To avoid long execution time for cloudfuzzer get-results, on remote, we should do periodic get-results on Bastion.

One alternative would be to setup a cronjob, for the sync. We also need to add some user-configuration option to enable/disable it.
