Check_MK Werk 5416: Prevent MS Exchange checks from crashing upon WMI timeout

ID: 5416 Title: Prevent MS Exchange checks from crashing upon WMI timeout Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i2 Werk #5411 introduced the identification and handling of WMI timeouts. Some of nested subsections, at least those of MS Exchange, may under certain circumstances produce an unprecedented order of output lines suddenly ending in a WMI timeout. This scenario was not expected when preparing #5411, causing the parsing of some MS Exchange subsections to fail and the corresponding check to crash. This fix ensures that a WMI timeout is properly parsed regardless of where it appears in a subsection output. The corresponding checks no longer crash but issue a PENDING/UNKNOWN result.
