debug: add new dubug level SSSDBG_PERF_STAT

SSSDBG_PERF_STAT should be use for statistical or performance data, e.g time needed for a request. :relnote: A new debug level is added to show statistical and performance data. Currently the duration of a backend request and of single LDAP operations are recorded if debug_level is set to 9 or the bit 0x20000 is set.
