Detect not accessible cron daemon [MAILPOET-801]

Browse Source 
This adds a function to a CronHelper which detect accessibility problem based on timestamps
which are stored during cron execution. The main idea is that the cron daemon should update run_started_at
within the REQUEST_TIMEOUT after it was accessed (run_accessed_at).
