cluster/dht: simplify and cleanup internal time management
Prefer time_t and gf_time() over 'struct timeval' and gettimeofday() where microseconds are not really used, drop unneeded 'struct timeval' to 'struct timespec' conversion in dht_file_counter_thread(). Change-Id: Ibd802f79b8848df3f6175ca1fd82e93532bba38d Signed-off-by: Dmitry Antipov <dmantipov@yandex.ru> Updates: #1002
