[sheepdog] [PATCH v2] dog: add elapsed time to measure the program is fast or not

Fri Jul 11 03:49:38 CEST 2014
To be compatible with OpenStack glance and cinder driver, we cannot
show elapsed time by default. Therefore, the new option -t (--time)
is added in dog command line to achieve it. For example:
dog cluster info -t
dog vdi check test -t
