include Robot log.html into check_MK

[simonmeggle]

HTML already gets transferred to Checkmk with commit #59

This issue covers the tasks on the CMK side.

Check:

• extract HTML log
• save within folder shared by site apache

Create an action menu for Robotmk checks which show two entries:

• "Show last log" -> links to the most recent log file
• "Show last non-OK log" -> links to the most recent log file of a non-OK state.

There won't be a long-term storage of HTML logs on the CMK side because the monitoring system should not be burdened with too much other tasks, including housekeeping. For more detailed analysis of e2e errors the logs on the client have to be inspected. See issue #91 (Configuring log rotation by state)

• Integrate Robotmk logo into MKP
