Provide more consistent man page examples within SAPHanaSR_maintenance_examples

1. Problem
   Sometimes there are real commands for the maintenance tasks examples written, but sometimes only the tasks are show.
   This man page is a very very important one as the maintenance task is done wrong by many admins.

2. Proposal
   Be more consistent with examples for the shown tasks.
   It's clear that this does not fit everywhere, but it would help the users.

3. Maybe a further way would be the new Smart Docs which describes a task step by step
