New slowlog format

I already success hacked new fpm slowlog like :

New config format(support microsecond):

                       <value name="request_slowlog_timeout">100000u</value> 
                       <value name="slowlog">logs/slow.log</value>

New slow log format(output query_string and exec_time) :
