Title: apache_status: Fixed exception when agent reports HTML code as apache-status data
Level: 1
Component: checks

Class: fix

When the apache-status module is not enabled or the webserver is somehow missconfigured,
the agents HTTP request to the apache-status URL might return HTML code instead of the
expected textual response. Added code to detect HTML code and skip the webserver instance
in this case.
