User story
As a user, I want to have the number of _include results (similarly to limiting _revinclude) so that I avoid potential performance issues.

Even though _revinclude is more risky, in terms of performance issue, it would be good to also limit _include results. The same limit applies when using the :iterate modifier.

Acceptance criteria

1. When I searching using _include and _revinclude modifiers, then the result sets per each _include/_revinclude parameter is limited by MaxCount, which is currently set to 100 by default.
