Ticket 48191 - Move CI test to the pr suite and refactor
    
    Description: Test suite for a new config parameter -
    nsslapd-maxsimplepaged-per-conn. The parameter should resctrict
    asynchronous simple paged results requests that could add too much load
    the server can handle.
    
    It tests three cases:
    - If no value or value: -1 - all users should be found;
    - If the value is 0 - UNWILLING_TO_PERFORM should be throwned
    - If the value is positive, the value is the max simple paged results
      requests per connection.
