sssctl: Showing help even when sssd not configured On a clean and unconfigured system, it's not possible to use --help. 1) dnf install sssd-tools 2) sssctl cache-remove --help Shows: [confdb_get_domains] (0x0010): No domains configured, fatal error! Solution: Donot check for confdb initialization when sssctl 3rd command line argument passed is '--help'. Please note when we run 'sssctl --help' on unconfigured system confdb check is not done and proper o/p is seen.

SSSCTL: Move sss_debuglevel to sssctl debug-level Move code from sss_debuglevel to sssctl_logs.c and add new debug-logs sssctl command to perform the same task of changing debug level dynamically. POPT_CONTEXT_KEEP_FIRST Flag added to poptGetContext call in sssctl_debug_level() to fix argument parsing.

TOOLS: Some tools command might not need initialization to succeed Since we want to use the sssctl tool during upgrade, we need to amend the tools initialization code to not error out if sysdb can't be instantiated, but rather return errno and let the tool handle the error. Each tool command now has a 'allowed errno' the command is able to handle. In this patch iteration, only a single errno can be handled and only the upgrade command is able to do so.
