Describe the issue you're reporting

Looking at the Prequisites for the Apache receiver, it claims to support version "2.4+". This implies, to me, any release in the 2.4 line.

I do not believe this is correct because some of the fields it scrapes do not appear until later versions of Apache. For example, ServerUptimeSeconds does not appear in mod_status until 2.4.13.

While this doesn't break the receiver when scraping the server-status endpoint from e.g. 2.4.6, it leads to metrics silently missing and users wondering "why some metrics are not going through".
