Documentation never specifies that an Include directive is processed immediately. 

My incorrect assumption was that you could put an Include parameter anywhere within a config file, and the directives contained within the included file(s) would only be processed AFTER everything in the current file.

This lead to confusing behaviour because the official shipped conf files for RHEL8 contain the Include= statement in the middle of the file (See ZBX-26982).

Please clarify the behaviour of the Include parameter.
