What does this PR do?

Format the {source,destination}.mac field as per ECS (https://www.elastic.co/guide/en/ecs/current/ecs-observer.html#field-observer-mac).

The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen.

Also add missing mappings for ECS event fields:

  • event.category
  • event.created
  • event.kind
  • event.original
  • event.timezone
  • event.type

lint was failing so I added type: date to the @timestamp. Issue reported in elastic/elastic-package#749.
