logging vty: add 'logging print timestamp', deprecate other timestamp cmds

Deprecate previous logging timestamp config commands:

  logging timestamp (0|1)
  logging print extended-timestamp (0|1)

Add new single timestamp configuration command:

  logging print timestamp (none|date-packed|ctime)

Another format called 'date' is added in patch
Icbd5192ea835e24b12fe057cc1ab56e9572d75c0. The idea is to have these
date formats:

 date         2018-01-16,01:44:34.681  (new, "best" format)
 date-packed  20180116014434681        (current 'print extended-timestamp 1')
 ctime        Sun Jan 1 01:44:34 2018  (current 'timestamp 1')
