[SSSD] [PATCH] sssctl: manual page

[Pavel Březina]

I don't think it is necessary to duplicate information from the tool 
itself into a manual page so a tried to keep the man page simple. This 
way we will not have to maintain it with any change in sssctl.

If you think it is better to include all commands and options in the man 
page as well, I can do it...
