Add date to show version (sonic-net#2086)

- What I did
Add the current date attribute to the "show version" output that includes the current date and hour on the switch.

- How I did it
In sonic-utilities, in the "version" subcommand, print of the current date will be added using "datetime" from the "datetime" library.

- How to verify it
Execute "show version" command and verify "Date" row under the "Uptime" row.
