Add mig2mozdef cron script

Script to get data from MIG using client-side SSL cert.

Send data to:
* doc_type='history'
* doc_type='last_known_state' with id: `md5('complianceitems"+check.ref+check.test.value+target)`

Ping me for a config files working with Mozilla deployment.
Worked with @jvehent on that.

Note: Works with SSLv3, not with TLS1.0/TLS1.1/TLS1.2!
debug print?
