Masahito Muroi f5da632a8e Enable lease-update to update start/end time with date
lease-update CLI only accepts time delta to update start_time
or end_time of leases. It's hard for users to specify a specific
date as its argument since users need to caluclate the time delta
between the previous start/end time and the new date.

This patch enables users to update leases with date format
like --end-date "2017-06-05 17:15".
