The `process-check-result` action can now optionally set the `ttl` parameter. This overrules the configured freshness check (check_interval). The main idea behind this is to allow the external sender to specify when the next check result is coming in. For example, a backup script which should be run every 24h can specify the exact expected next check result. The addition to the CheckResult class is necessary to forward the check result throughout the cluster and calculate the `next_check` value on each node. This allows us to send in a check result on a satellite, and the master determines the freshness and possible notifications/state changes for Icinga Web 2.

Scalable and extensible, Icinga 2 can monitor large, complex environments across multiple locations.
Icinga 2 as monitoring core works best with Icinga Web 2 as web interface.
