Bugfix: change date format in hp_comware_display_clock.textfsm (#977)

As per
https://techhub.hpe.com/eginfolib/networking/docs/switches/5940/5200-1008b_fund_cr/content/491962772.htm
output of the `display clock` commands output contains date in `MM/DD/YYYY`
format. Can confirm this on different types of HPE switches I have at my disposal.

Added test cases that cover the scenarios when time zone and daylight time
saving configurations are set.
