Check_MK Werk 5271: Better handling of erroneous deployment information in Agent Bakery

ID: 5271 Title: Better handling of erroneous deployment information in Agent Bakery Component: agents Level: 1 Class: Bug fix Version: 1.5.0i3 Depending of the state of the agent deployment information file for a host, the pages "Automatic agent updates" and "Agent update status" would crash and show only partial information. This is now mitigated by handling corrupt agent deployment files per-host and displaying an error message in a convenient format and location on the affected pages.
