Foreman Maintain

Currently, we have added runtime_message method which shows description + param details.
For some procedure, we don't need to show param details in round brackets.

As in "investigate the tasks via UI" procedure it showing below output:

1. ./bin/foreman-maintain health check
   Running ForemanMaintain::Scenario::FilteredScenario ================================================================================
   Check for verifying syntax for ISP DHCP configurations: [OK]
   --------------------------------------------------------------------------------
   check for paused tasks: [FAIL]
   There are currently 46 paused tasks in the system

   There are multiple steps to proceed:
   1) resume paused tasks
   2) investigate the tasks via UI ({:search_query=>#<ForemanMaintain::Param:0x000000012cb400 @name=:search_query, @description="", @options={}, @required=false, @flag=false, @block=nil, @array=false>})
   Select step to continue, [n(next), q(quit)] 2
